help:
Syntax: help
help name
Description:
help : Prints a list of available help files. Help first
prints out the help files in the default help file
directory. Next, the directories identified in the
environment variable RLAB_SEARCH_PATH are searched for
files ending in `.r' -- rfiles. A list of each
directory's rfiles is printed on the standard output.
help name : Prints out the help file identified by name. If
name matches a file in the default help directory, that
file is paged to the standard output. If no match is
found, the directories identified in the environment
variable RLAB_SEARCH_PATH are searched for matches. The
first match is paged to the standard output. The rfile
extension (`.r') is not considered when checking for
matches.
If the user's environment does not contain RLAB_SEARCH_PATH,
then the default search-path is used. The default is set at
compile time. Normally the default is ".", the current working
directory.
Help is a command, not an expression or statement. Therefore,
it must be issued on a line by itself, and cannot occur in the
midst of another statement or expression. See `help COMMAND'.
Help files that are spelled with uppercase letters contain
general information, or information on keywords. For instance,
`help MATRIX' provides general information about matrix usage,
`help IF' provides help on if statements.
