- COMMAND:
-
- The RLaB language has a several commands, they are listed
- below. Commands are different than functions, in that they do
- not require parentheses to delimit the function argument(s).
-
- Commands may not occur anywhere in an expression or statement.
- Commands must be issued from the command line prompt, on a
- line by themselves.
-
- Commands:
-
- help The help command, without an argument, prints a listing
- of the available help files. The help command can take
- a single argument, that is the name of a help
- file. The named help file will be paged to the screen
- (stdout). See `help help'
-
- rfile The rfile command, without argument(s), prints a
- listing of the available rfiles. The rfile command can
- take one, or several arguments, that are the names of
- help files to be loaded into the current rlab
- environment. The rfile argument(s) can be the full
- file name (ending in `.r'), or a shorthand for the
- file name (without the `.r' extension).
- See `help rfile'
-
- require The require command is similar to the rfile
- command. See `help require'
-
- \ When a backslash is the first character on the command
- line, the rest of the command line is fed to the
- system() function. Thus:
-
- system ("ls *.r");
-
- and
-
- \ ls *.r
-
- produce the same result.
