Rcmdr.Utilities {Rcmdr} | R Documentation |
These functions support writing additions to the Rcmdr package. Additional R code
can be placed in files with file type .R
in the etc
subdirectory
of the package. Add menus, submenus, and menu items by editing the file
Rcmdr-menus.txt
in the same directory.

command |
a character string that evaluates to an R command. |
dsname |
the name of a data frame, as a character string; if not specified, the name of the active data set is returned. If there is no active data set, then an error dialog is generated. |
envir |
the environment to be searched; should generally be left at the default. |
model |
the name of a model, as a character string; if not specified, the name of the active model is returned. If there is no active model, then an error dialog is generated. |
x |
a putative R object name, as a character string. |

The functions doItAndPrint
, justDoIt
, and logger
control the
execution, logging, and printing of commands generated by menus and dialogs.
logger(command)
adds command
to the log window and, with the pseudo-prompt
R-cmdr>
, to the R session window. justDoIt(command)
causes command
to be executed. doItAndPrint(command)
does both of these operations.
The function is.valid.name
checks whether a character string specifies a valid name
for an R object, returning TRUE
or FALSE
.
The other functions are self-explanatory.
