- Statistical Modes Help
-
-
- help version: 2.1
- created: 03/07/00 {01:10:49 am}
- last update: 01/04/01 {09:45:12 am}
-
-
- This document describes four statistical modes for the software Alpha.
- They include SAS, S (for S, S-Plus, and R), SPSS, and Stta (Stata).
-
- This help manual is rather long, because it deals with all four of these
- modes -- each section assumes that you didn't read anything about the
- others. The "General Notes" section, however, does contain information
- that relates to all of them.
-
-
- Description of files
-
-
- The first four contain the bulk of each mode's variables and procedures:
-
- SAS "sasMode.tcl" (version 2.1)
- S "sMode.tcl" (version 2.1)
- SPSS "spssMode.tcl" (version 2.1)
- Stta "stataMode.tcl" (version 2.1)
-
-
- The next eight are for <mode>Completions, and Completion Tutorials:
-
- "SASCompletions.tcl"
- "SAS Tutorial.sas"
-
- "SCompletions.tcl"
- "S Tutorial.s"
-
- "SPSSCompletions.tcl"
- "SPSS Tutorial.sps"
-
- "SttaCompletions.tcl"
- "Stta Tutorial.do"
-
- Finally, there is one help file (the one you're currently reading):
-
- Statistical Modes Help
-
-
- General Notes About The Modes
-
-
- (1) These modes serve primarily to make it easier to write statistical
- syntax files -- they colorize, and set some electric, word break,
- and commenting preferences.
-
- Each mode includes its own menu, allowing Alpha to act as a "front
- end" for the Macintosh version of the application. (Note that in some
- cases the processing of files or selections may still be in beta stage.)
-
- The menu for each mode includes "Help", "Keywords", and "Mark As"
- submenus that contain items for obtaining command information,
- setting mode specific preferences, checking or adding new keywords, and
- marking the current window as either source or output files.
-
- (2) Each mode contains a full set of electric completions, as well as a
- Completions Tutorial via the "Config --> Mode Prefs" menu item.
-
- (3) Example syntax files are available via the "Mode Examples Help" file.
- If you open an example syntax file through the provided hyperlinks, it
- will open in a "shell" window. After you close the window, clicking
- on the hyperlink will return the unblemished original.
-
- (4) All of these modes allow for user customization of keyword dictionaries
- via the "Config --> Mode Prefs --> Preferences" dialog. New keywords
- and color changes will take effect immediately, without the need for
- a restart or changing windows. Keywords can also be added using some
- of the menu items found in each menu's "Keywords" submenu -- using the
- "Add New Commands" item, you can optionally add all of the "extra"
- commands which appear in the current window.
-
- Each section below includes a brief overview of the statisitical
- package's nomenclature, and a hyperlink to the installed .tcl file
- which contains the keyword dictionaries.
-
- (5) Instructions for editing a <mode>Prefs.tcl file are given in each
- section. Any keywords added will not only be colorized, but included
- in the completions routines as well.
-
- (6) All of these modes use the Electric Return, Tab, and Braces features.
- These could, of course, be turned off. Each mode recognizes both
- the continuation and the end of commands, indenting appropriately.
- The indentation amount can be set in the "Config --> Electrics" menu.
-
- One could also take advantage of Alpha's "electric return override"
- key binding. Pressing control-return will place the cursor on the
- next line without any indentation.
-
- (7) Each mode has navigation menu items, bound to control-shift N and P.
- These items are also bound to control-shift arrow keys, and to 1 and 3
- on the keypad when the num-lock is turned off.
-
- Control-shift up and down will find the prev/next command. The right
- and left arrow keys not only find prev/next commands, but will also
- place the cursor at the top of the window.
-
- (8) Each mode has its own indentation scheme, based upon unbalanced braces
- and (for Stata, SPSS, and SAS) on whether the previous command was
- properly terminated. Entire commands can also be highlighted with
- control-shift S, or reformatted (aligning indentation) with
- control-command I.
-
- The "Full Indent" mode preference determines if continued commands are
- indented to the full "Indentation Amount" (which can be set using
- "Config --> Preferences --> Electrics" menu item), or just half of
- this value.
-
- (9) Each mode has Mark File [M] and Parse Function {} capabilities.
- Each marking routine can recognize either source or output files.
-
- Selecting the "Auto Mark" preference, available as a toggleable menu
- item in each mode's "Mark As…" submenu, will automatically mark a file
- when it is opened, assuming that no previous marks yet exist for the
- file.
-
- (10) Finally, on-line help is available for each mode through command
- double-clicking. The url to which the keywords are sent can be
- configured the the "Mode Prefs --> Preferences" dialog. Each menu
- also includes a "Home Page" option, using the url set in this dialog.
-
-
- ======================================================================
-
-
- SAS
-
-
- This is also a goood mode for reading SAS output files. One could easily
- add a preference in the "Config --> Preferences --> Suffix Mappings" menu
- item to automatically recognize .lst or .log files.
-
- Example syntax file: "SAS Example.sas"
-
-
- SAS Keywords
-
-
- SAS seems to have five levels of possible keywords, all of which can be
- reviewed in "sasMode.tcl" :
-
- 1. the top level "proc" command: anova, freq, varcomp
- 2. sub-level procs, or "subprocs": rename, value, range
- 2. "arguments", which require no parameters: ls, missover, in1
- 3. "options", which require parameters: converge, data, gamma
- 4. "parameters", preset as opposed to user supplied: full, part
-
- The default setup of this mode is to colorize all of procs and subprocs
- blue; arguments, options, and parameters are magenta. The user does not
- have to specify all of these different levels -- only Argument, Command,
- Comment, String, and Symbol colors appear in the preferences.
-
- Each of these commands has an electric completion available, and the mode
- comes with a Completions Tutorial, available in the "Config --> Mode Prefs"
- menu item. Using the completion key, which can be defined with the menu
- item "Config --> Special Keys", the user can type
-
- p'ano<complete>
-
- and Alpha will automatically insert the following text:
-
- proc anova | ;
- •
-
- The template stops will allow the user to use the tab key to jump ahead to
- insert the needed variable names, and the last stop will position the
- cursor for the next command.
-
- Additional commands and arguments can be added in two ways, through the
- Mode Preferences menu item, and in a SASPrefs.tcl file. Extra keywords
- defined (using either method) will be included in the electric completion
- routines. The "Keywords --> Add Commands" menu item will give you the
- option to add all "extra" commands in the current file to the "addCommands"
- mode preference.

-
- SAS Menu
-
-
- Switch To SAS
-
- Launch SAS into foreground.
-
- Process File
- Process Selection
-
- Send window (or the highlighted selection) to SAS for processing.
-
- Insert Path
-
- Open a dialog to select a file, and then insert the file's pathname.
-
- Next Command
- Prev Command
-
- Navigate the current window, defining the next/prev command based upon
- non-commented text in column 1 of any row.
-
- Navigation commands are also bound to control-shift arrow keys, as well as
- the 1 and 3 keys on the keypad when num-lock is turned off.
-
- Select Command
-
- Select the entire command to its termination.
-
- Reformat Command
-
- Reformat the current command surrounding the cursor, aligning indentation.
-
-
-
- SAS command double-click
-
-
- On-line help is available for SAS commands through command-double-clicking.
-
- SAS provides a help file suite called SAS OnlineDoc. The license agreement
- suggests that access should be restricted to users within a particular
- domain. If you have access to this set of files (either locally on your
- hard drive or within via a protected domain location), you should set the
- url preference in the mode preferences dialog.
-
- (Occassionally you can find versions that are open to the public. Try the
- search term "SAS Online Doc".)
-
- Any available syntax information is also available by pressing the control
- key while command-double-clicking. This information will appear in the
- status bar window. In some cases, this information is too long to be read
- in its entirety. Pressing the shift key instead of the control key will
- insert this syntax information as commented text into your current window.
-
- NOTE: These control-command and shift-command double-click features have
- not been fully implemented. See the "SASCompletions.tcl" file for
- additional information.
-
-
-
- SAS File Marking
-
-
- For SAS mode, Mark File will return the first 35 characters of each command
- which begins a new line. Therefore it should not include any indented or
- continued commands. Headings will be marked, defined by three (and only
- three) comment characters and a space at the start of a line. Subheadings
- are indicated by four comment characters.
-

- command varlist (options) command varlist (options)
-
-
- Function parsing {} will return only the command name, in alphabetical order.
-
- Mark File mode will check to see if the current window is a .sas file. If
- it is not, it will assume that it is an output file, and Alpha will adjust
- its marking and parsing routines accordingly.
-
-
- Adding an SAS Prefs file
-
-
- To add additional commands or arguments in a "SASPrefs.tcl" file, go to
- "Config --> Mode Prefs --> Edit Prefs File", and add these lines:
-
-
- set SASUserCommands {
- blah bladdity
- }
-
- set SASUserArguments {
- blah2 bladdity2
- }
-
- SAS::colorizeSAS
-
-
- Include as many keywords as desired within the braces, separating each
- keyword by at least one space or carriage return. Alpha will automatically
- load this preferences file the first that the SAS mode is invoked.
-
- Any keywords contained in these categories will not only be colorized, but
- will also be included as electric completions. Don't repeat commands or
- arguments that have already been defined.
-
-
- ======================================================================
-
-
- S (S-Plus, R)
-
-
- This mode is for editing S source files. Keywords are primarily based on
- release number 3.3, taken from the 'common commands' as listed in Venable
- and Ripley's Modern Applied Statistics with S-PLUS, second edition. This
- would be a good mode for R files, too, but the C mode has already laid
- claim to the suffix .r -- this could be changed in Alpha's suffix mappings.
-
- Example syntax file: "S Example.s"
-
-
- S-Plus Keywords
-
-
- S-Plus is remarkably elegant in structure. Commands have arguments, and
- rarely does the language use the same names for both. There are a few
- exceptions, which reside in the Arguments category. These exceptions could
- be changed to commands through the "Mode Prefs --> Preferences" dialog.
-
- The Venable and Ripley MASS library can also be included in keyword lists for
- both colorizing and completions by checking the Use Mass Library preference.
-
- Keywords can be reviewed in "sMode.tcl" .
-
- Each of these commands has an electric completion available, and the mode
- comes with a Completions Tutorial, available in the "Config --> Mode Prefs"
- menu item. Using the completion key, which can be defined with the menu
- item "Config --> Special Keys", the user can type
-
- glm<complete>
-
- and Alpha will automatically insert the following text:
-
- glm(| ~ •)•
- •
-
- The template stops will allow the user to use the tab key to jump ahead to
- insert the needed variable names, and the last stop will position the
- cursor for the next command.
-
- Additional commands and arguments can be added in two ways, through the
- Mode Preferences menu item, and in an SPrefs.tcl file. Extra keywords
- defined (using either method) will be included in the electric completion
- routines. The "Keywords --> Add Commands" menu item will give you the
- option to add all "extra" commands in the current file to the "addCommands"
- mode preference.
-
-
- Completions Tutorial: "S Tutorial.s"
-
-
- S mode Carriage Returns
-
-
- S mode has its own indentation scheme, based upon unbalanced braces, and
- uses the Electric Return, Tab and Braces features. Each time that you
- start a new line with the <return> key, the previous non-commented line is
- evaluated for unmatched ( and ) -- ignoring any braces that appear within
- double quotes or after valid comment characters.
-
- Lines that begin with ) will have their indentation reduced by one level to
- match the line with the matching (, as in
-
- for (i in 1:length(data03.1$year)){
- data03.1$year <- as.vector(data03.1$year)
- if(data03.1$year[i] == "1965-70") (
- data03.1$year[i] <- c("1965-69")
- )
- }
-
- In some cases, as when you are continuing a command, you might want to
- over-ride this behavior. For example, if you type
-
- qqno|
-
- and press the completion key, the command completes to
-
- qqnorm(|)••
-
- Typing "resid" and pressing the completion key again turns the line into
-
- qqnorm(resid(|)••)••
-
- If you type some more text and then press <return>, the next line will
- automatically indent to
-
- qqnorm(resid(out3.11), ylab = "deviance residuals",
- |)••
-
- which is properly indented. This would be fine if this line actually
- terminated the command, but you might want to continue the command. To
- over-ride this behavior, which in this case would increase the level of
- indentation for the next line to 1, press <shift>-<return> instead:
-
- qqnorm(resid(out3.11), ylab = "deviance residuals",
- |)••
-
- and then some more text and a regular carriage return will make the command
- look like
-
- qqnorm(resid(out3.11), ylab = "deviance residuals",
- xlab = "extremities"
- )
-
- Entire commands can also be reformatted (aligning indentation) with
- <control>-<command> I.
-
- To enter a carriage return with no indentation whatsoever, press
- <control>-<return>.

-
-
- ======================================================================
-
-
- SPSS
-
-
- This is also a goood mode for reading SPSS output files. One could easily
- add a preference in the "Config --> Preferences --> Suffix Mappings" menu
- item to automatically recognize .out or .log files produced by SPSS.
-
- Example syntax file: "SPSS Example.sps"
-
-
- SPSS Keywords
-
-
- SPSS does a lousy job of naming things, or at least is more than willing to
- give a keyword (as in SPSS keyword) the same name as a function, statement,
- subcommand or command. There's little point in trying to distinguish
- amongst all of this with different colors, because it just won't work.
- Instead, they are included one long list, called "commands." There's also
- a short list of functions (abs, arsin, artan, etc) as well as several
- operators (all, and, by, eq, ge, gt, into, etc).
-
- Keywords can be reviewed in "spssMode.tcl" .
-
- Each of these commands has an electric completion available, and the mode
- comes with a Completions Tutorial, available in the "Config --> Mode Prefs"
- menu item.
-
- Additional commands and arguments can be added in two ways, through the
- Mode Preferences menu item, and in an SPSSPrefs.tcl file. Extra keywords
- defined (using either method) will be included in the electric completion
- routines. The "Keywords --> Add Commands" menu item will give you the
- option to add all "extra" commands in the current file to the "addCommands"
- mode preference.
-
-
- Completions Tutorial: "SPSS Tutorial.sps"
-
- Non-ambiguous SPSS keywords
-
-
- SPSS allows .sps files to contain non-ambiguous command and option
- abbreviations. It would be nice if Alpha could colorize based upon the
- location of keywords, but as of this writing it cannot. Creating a list
- of all possible abbreviations is also out of the question, which presents
- a challenge for both this mode's maintainer and the user to effectively
- colorize a syntax file. Fortunately, two solutions are available.
-
- The first is to utilize the electric completions that are available. Using
- the completion key, which can be defined with the "Config --> Special Keys"
- menu item, the user can type
-
- regr<complete>
-
- and Alpha will automatically insert the following text:
-
- regression | • • .
- •
-
- The template stops will allow the user to use the tab key to jump ahead to
- insert the needed variable names, and the last stop will position the
- cursor for the next command. This way unambiguous abbreviations need only
- be typed, though the full command will appear and be colorized. SPSS mode
- has a completions tutorial available, accessed by "Config --> Mode Prefs".
-
- The second solution is to define common abbreviations through either the
- "Config --> Mode Prefs --> Preferences" menu item or a "SPSSPrefs.tcl" file.
- These will be automatically included in the completion routines as well,
- and the actual text to be inserted can be refined by the user using the
- "Config --> Mode Prefs --> Edit Completions" menu item.

-
- SPSS command double-click
-
-
- On-line help is available for SPSS commands through command-double-clicking.
- The URL to which the keywords are sent can be changed through the Mode
- Preferences dialog.
-
- The default URL is a search engine for the GNU PSPP project. PSPP is a
- statistical analysis program. It is an upwardly compatible replacement of
- the proprietary statistical analysis program SPSS. A main goal of the PSPP
- project is compatibility with the SPSS language. PSPP also aims to be
- written better than the program it replaces. For more information, see
-
- <http://www.gnu.org/software/pspp/>
-
-
- Any available syntax information is also available by pressing the control
- key while command-double-clicking. This information will appear in the
- status bar window. In some cases, this information is too long to be read
- in its entirety. Pressing the shift key instead of the control key will
- insert this syntax information as commented text into your current window.

-
- There is also a special marking routine for files produced by the FREQ
- command, available in the "SPSS --> Mark Spss File As …" menu. Mark File
- will then contain only the variable names, and list them in alphabetical
- order. Extremely handy for data sets with a lot of variables. (Note that
- because SPSS output doesn't allow for unambiguous recognition of these

-
-
-

-
-
- Stata
-
- This is also a goood mode for reading Stata output files. One could easily
- add a preference in the "Config --> Preferences --> Suffix Mappings" menu
- item to automatically recognize .out or .log files.
-
- Keywords are based on release 6.0.
-
- (Thanks to L. Philip Schumm for several contributions, including the Stata
- menu, the <shift>-<return> key binding, and other useful suggestions.)
-
- Example syntax file: "Stata Example.do"
-
-
- Stata Keywords
-
-
- Stata has five levels of processes.
-
- 1. commands, subcommands, prefixes: mlogit, define, quietly,
- 2. parameters: textsize, maxobs, width, more,
- 3. functions: abs(), log(), sin(), ge, lt,
- 4. options: noheader, bar, adjust, iterate
- 5. modifiers: [weights= ], [frequency= ]
-
- and, just to help make sure that everything goes smoothly, we have
-
- 6. out of date (or "dated") commands: genrank, grebar
-
- Keywords can be reviewed in "stataMode.tcl" .
-
- For the most part, Stata is very good about not using the same name for a
- command to refer to a function, parameter, or modifier. Options, however,
- often have the same names as commands.
-
- The default setup of this mode is to colorize all of commands, subcommands,
- prefixes, parameters, and macros blue. Options, functions, modifiers, and
- symbols are colorized magenta. Dated commands are red. The user does not
- have to specify all of these different levels -- only Command, Comment,
- Option, String, and Symbol colors appear in the preferences.
-
- Additional commands and options can be added in two ways, through the Mode
- Preferences menu item, and in a SttaPrefs.tcl file. Extra keywords defined
- (using either method) will be included in the electric completion routines.
- The "Keywords --> Add Commands" menu item will give you the option to add
- all "extra" commands in the current file to the "addCommands" mode
- preference.
-
-
-
- Non-ambiguous Stata abbreviations
-
-
- Stata allows .do files to contain non-ambiguous command and option
- abbreviations. It would be nice if Alpha could colorize based upon the
- location of keywords, but as of this writing it cannot. Creating a list
- of all possible abbreviations is also out of the question, which presents
- a challenge for both this mode's maintainer and the user to effectively
- colorize a syntax file. Fortunately, two solutions are available.
-
- The first is to utilize the electric completions that are available. Using
- the completion key, which can be defined with the "Config --> Special Keys"
- menu item, the user can type
-
- mlog<complete>
-
- and Alpha will automatically insert the following text:
-
- mlogit | • • ;
- •
-
- The template stops will allow the user to use the tab key to jump ahead to
- insert the needed variable names, and the last stop will position the
- cursor for the next command. This way unambiguous abbreviations need only
- be typed, though the full command will appear and be colorized. Stta mode
- has a completions tutorial available, accessed by "Config --> Mode Prefs".
-
- The second solution is to define common abbreviations through either the
- "Config --> Mode Prefs --> Preferences" menu item or a SttaPrefs.tcl file.
- Both methods allow for keywords to be defined as either commands or options.
- The "Keywords --> Add Commands" menu item will give you the option to add
- all "extra" commands in the current file to the "addCommands" mode
- preference.
-
- These will be automatically included in the completion routines as well,
- and the actual text to be inserted can be refined by the user using the
- "Config --> Mode Prefs --> Edit Completions" menu item.

- Finally, one could always define the Command and Option Colors to be the
- same, which would avoid some (though certainly not all) of these issues.
- Setting both colors to "none" will remove this issue entirely !!

-
- Command line delimiter
-
-
- In Stata, the end of a command line may be indicated with either a carriage
- return or a semicolon. Carriage return is the default, and most Stata
- programmers (including the official code released by StataCorp) stick with
- this. This means that splitting a single command into two or more physical
- lines requires using the comment characters /* and */.
-
- The key-binding <shift>-<return> will insert these characters.
-
- The "Stata --> Stata Help" menu includes the item "Semi Delimiter", which
- should be set if you terminate commands with the semicolon. This
- preference is used in all completion routines, and to determine if the next
- line should be indented following a carriage return. The "Reformat
- Command" menu item will also respect this preference when re-aligning
- indentation. The menu item "Indentation Amount" sets the Stta mode
- preference of the same name, which determines how much white space will be
- inserted when continuing a command.

-
-
- Switch To Stata - launch Stata into foreground.
-
- Launch Stata into foreground.
-
- From within Alpha, shift-cmd-S will take you to Stata. And if you do not
- have any open applications whose names come before Alpha or after Stata
- (alphabetically, that is), then cmd-Tab will take you from Stata back to
- Alpha (assuming that you have the Application Switcher enabled and
- configured appropriately). If you need help configuring the Application
- Switcher, you may obtain it by looking under the topic "Switching between
- open programs" in the Macintosh Help Viewer.
-
- Note that launching Stata via the Stata menu has the same result as
- double-clicking on the Stata application (as opposed to clicking on a do
- file). This means that when Stata comes up the working directory will be
- the same directory in which the Stata application resides, and it is not
- generally advisable to save files there. The best way around this is to
- create a profile.do file containing a -cd- command, and place it in this
- directory so that it is automatically executed whenever Stata is launched.
-
- Do File
- Do Selection
-
- Send window (or the highlighted selection) to Stata for processing.
-
- When Stata processes a do-file, it ignores the last line unless the file
- ends with a carriage return. Stata's do-file editor is smart about this,
- and automatically adds a carriage return (if necessary) when you save the
- file. Stat mode will add a carriage return (if necessary) when you send a
- file to Stata for processing, but will not do so if you simply save the
- file. Keep this in mind.
-
- Insert Path
-
- Open a dialog to select a file, and then insert the file's pathname.
-
- Program Template
-
- Insert a template for writing a program (useful for simulations and
- bootstrapping). See the notes below on editing a SttaPrefs.tcl file for
- information on customizing this template.
-
- Continue Command
-
- Continue the current command, by inserting */
- */ at the current location of the cursor.
-
- Next Command
- Prev Command
-
- Navigate the current window, defining the next/prev command based upon
- non-commented text in column 1 of any row.
-
- Navigation commands are also bound to control-shift arrow keys, as well as
- the 1 and 3 keys on the keypad when num-lock is turned off.
-
- Select Command
-
- Select the entire command to its termination.
-
- Reformat Command
-
- Reformat the current command surrounding the cursor, aligning indentation.
-
-
- Stata command double-click
-
-
- On-line help is available for Stata commands via command-double-clicking.
- The URL to which the keywords are sent can be changed through the Mode
- Preferences dialog.
-
- Clicking on a program name that has been defined in the current window will
- move the cursor to that program's definition, as in
-
- program define dothis ;
-
- regress `1' ...
- ...
-
- end ;
-
- Pressing control-. will return the cursor to its original position.
-
-
- Control, Shift, Option modifiers
-
- Any available syntax information is also available by pressing the control
- key while command-double-clicking. This information will appear in the
- status bar window.
-
- In some cases, this information is too long to be read in its entirety.
- Pressing the shift key instead of the control key will insert this syntax
- information as commented text into your current window.
-
- Finally, pressing the option key on a command will open the corresponding
- local Stata application .hlp file if it exists. Note that you can also set
- Stata so that it automatically performs a search for the command (or word)
- if a .hlp file is not located. To re-assign command double-click to local
- search as well (without having to using the option modifier), check the
- "Local Help Only" box in the Mode Preferences.
-
-
- Stata File Marking
-
-
- For Stta mode, Mark File will return the first 35 characters of each command
- which begins a new line. Therefore it should not include any indented or
- continued commands. Headings will be marked, defined by three (and only
- three) comment characters and a space at the start of a line. Subheadings
- are indicated by four comment characters.
-
-
- The File The Mark
- ________ ________
-
- *** Section Heading • Section Heading
- **** Subsection Heading * Subsection Heading
- command varlist (options) command varlist (options)
-
-
- Function parsing {} will return only the command names, in alphabetical order.
-
- Mark File mode will check to see if the current window is a .do or .ado
- file. If it is not, it will assume that it is an output file, and Alpha
- will adjust its marking and parsing routines accordingly.
-
- There is also a special marking routine for files produced by the .codebook
- command, available in the "Stata --> Mark Stata File As …" menu. Mark File
- will then contain only the variable names, and list them in alphabetical
- order. Extremely handy for data sets with a lot of variables.
-
-
- Adding a Stata Prefs file
-
-
- To add additional commands or arguments in a "SttaPrefs.tcl" file, go to
- "Config --> Mode Prefs --> Edit Prefs File", and add these lines:
-
-
- set SttaUserCommands {
- blah bladdity
- }
-
- set SttaUserOptions {
- blah2 bladdity2
- }
-
- Stta::colorizeStta
-
-
- Include as many keywords as desired within the braces, separating each
- keyword by at least one space or carriage return. Alpha will automatically
- load this preferences file the first that the Stta mode is invoked.
-
- Any keywords contained in these categories will not only be colorized, but
- will also be included as electric completions. Don't repeat commands or
- options that have already been defined.
-
- To modify the text inserted by the "Program Template" menu item, place this
- procedure in a "SttaPrefs.tcl" file, and modify the text defined in the
- "pt" variable:
-
- proc Stta::programTemplate {} {
-
- Stta::SttaModeMenuItem
-
- global SttamodeVars
-
- set end [lindex [Stta::getCommand [getPos]] 1]
- if {$end != "-1" && $end > [getPos]} {
- goto $end
- }
- if {$SttamodeVars(semiDelimiter)} {
- set eol " ;\r"
- } else {
- set eol "\r"
- }
-
- set pt "program define •progname•${eol}\tversion 6.0${eol}\tif \"`1'\""
- append pt " == \"?\" {\r\t\tglobal S_1 \"•variable names•\"${eol}\t\t"
- append pt "exit${eol}\t}${eol}\t••\r\t* (each result below must correspond"
- append pt " to a variable in S_1)${eol}\tpost `1' •results•${eol}end${eol}"
- elec::Insertion $pt
- }
-
-
-
- Stta mode Known Bugs
-
-
- If you use a profile.do file to execute a set of commands automatically
- whenever Stata is launched (as is suggested above), then you must wait a
- few moments (depending upon the speed of your computer and what commands
- are in the file) after launching Stata before it is ready to respond to
- your input. Stta mode doesn't know this, and therefore when you send a
- file or a selection to Stata for processing without Stata already running,
- Stata is launched and the file sent so quickly that an error may occur. If
- you are experiencing this problem, use shift-cmd-S to launch Stata first.

-
- Updated versions will also be posted to Vince's upload site,
-
- <ftp://ftp.ucsd.edu/pub/alpha/>
-
- and announced on the ALPHA-D mailing list. This is a mailing list for
- Alpha where you can discuss problems, suggest new features etc. To
- subscribe, email <listserv@listserv.syr.edu> and, in the body of your
- message (not the subject line), write:

-
- Future Versions
-
-
- These modes are submitted to the Alpha community with the hopes that (i)
- somebody else will find them useful, (ii) any errors or updates will be
- reported to the mode's maintainer, and (iii) they might inspire somebody to
- take them even further. I will continue to maintain them and post updates
- as necessary, but any contributions are certainly welcome.
-
- Commercial statistical packages are updated with some regularity.
- Chances are that the keyword dictionaries contained herein will need an
- occasional facelift. Don't be shy, especially if you have a manual for
- the newer versions handy.
-
- Could Alpha be used as a front end for any of SAS or SPSS? I don't know.
- To be honest, I've never used any of these statisical packages on a
- Macintosh before -- I have always worked in an academic setting which has
- provided site licenses for the Unix versions. I do all of my text-editing
- work on a Macintosh, however, saving the files in my Unix account. When I
- need to actually run the syntax files, I do so with a telnet window.
-
- This is admittedly an idiosyncratic arrangement -- but it's all based on
- division of labor needs, for which Alpha is ideally suited. I have neither
- the Tcl nor the Apple Event knowledge to try to make Alpha interface with
- these programs. If anybody else wants to give it a try ...
