Rcmdr (version 0.9-8)

Rcmdr.Utilities: Rcmdr Utility Functions

Description

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.

Usage

activeDataSet(dsname)
activeModel(model)
doItAndPrint(command)
justDoIt(command)
is.valid.name(x)
listDataSets(envir = .GlobalEnv, ...)
listGeneralizedLinearModels(envir = .GlobalEnv, ...)
listLinearModels(envir = .GlobalEnv, ...)
logger(command)

Arguments

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.

...

Disregard.

Details

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.
