PMG

1  PMG

The pmg package for R provides a relatively simple graphical user interface for R in a manner similar to the more mature Rcmdr package. Basically this means a menu-driven interface to dialogs that collect arguments for R functions. This GUI was written with an eye towards simplifying the learning curve of R for introductory statistics students.
The pmg package uses the gWidgets package.
The pmg package uses the GTK toolkit via the RGtk2 package by Michael Lawrence. Some features are
  • The GUI works under Windows, Mac OS X, Linux/X11
  • The GUI takes advantage of GTK's drag-and-drop capabilities.
  • Several dialogs for analyses performed in an introductory statistics course can be used simply by dragging variables around.
  • With the cairoDevice package, the GUI provides a notebook interface to a graphics device that allows UNIX users to easily manage multiple graphics devices.

2  Installation

Installing pmg requires two steps: installing the GTK libraries and installing the R packages.
If the GTK libraries are already installed, then pmg may be installed with 
> install.packages("pmg", dep=TRUE)
(You may need type=ßource" under Mac OS X.)
For Windows users, the following command automates the installation including installing GTK if needed: 
> source("http://www.math.csi.cuny.edu/pmg/installpmg.R")
For Mac OS X users, the gtk libraries can be found bundled up at http://r.research.att.com/gtk2-runtime.dmg. These are to be run from within an X11 session (not the R GUI for Mac).

2.1  Installing the R packages

The following R packages are needed: RGtk2, cairoDevice, gWidgets, gWidgetsRGtk2, and pmg. Install them in this order, as some depend on others to be installed first. All can be downloaded from CRAN.
As the "Suggests" value for pmg contains gWidgets and gWidgetsRGtk2 which in turn suggest RGtk2 and cairoDevice this can be achieved from the command line with 
   install.packages("pmg", dep = TRUE)
You may need to adjust the location where the libraries will be installed if you do not have the proper permissions.

3  Try out pmg

The package may be started with 
> library(pmg) 
A screenshot can be seen at http://www.math.csi.cuny.edu/pmg/Screenshots.
If the GUI Is closed, it may be restarted with the command pmg().
The pmg package provides a short vignette with some examples. You may read this with the command 
>    vignette("pmg") # read about some examples

4  gWidgets

The pmg GUI is written using the gWidgets package. This package trades off the power of directly using RGtk2 for a more R-like interface. It can be used independently of pmg or to add to pmg. To learn more see http://www.math.csi.cuny.edu/pmg/gWidgets.
