[R-gui] New versions of gWidgets, gWidgetsRGtk2, pmg, and a new package gWidgetsrJava

[j verzani]

Dear GUI-list readers,

I uploaded to CRAN today updated packages for gWidgets (0-12),
gWidgetsRGtk2 (0-12) and pmg (9-28). As well, I added a new package
gWidgetsrJava (0-1).

The gWidgets package sets up an API for interacting with graphical
toolkits within R to create GUIs. An accompanying vignette has many
examples of its usage. This package needs a further package
integrating the API with a specific graphical toolkit.

The gWidgetsRGtk2 package allows the RGtk2 package to be used within
this framework. The new gWidgetsrJava package does a similar thing for
rJava.

The gWidgetsrJava package is not nearly as complete as the one for
RGtk2, but might be of interest. It must run from within the JGR
environment to be interactive.   This package borrows heavily from
Simon's iWidgets package, but adds some more features.

The pmg package provides a lightweight GUI for R, similar to RCmdr,
which uses gWidgetsRGtk2 to provide drag and drop and other features
to the GUI. Some of the dialogs are quite interactive, others
basically collect arguments to pass along to an R function.

The pmg package has an accompanying vignette documenting its usage.

Some installation details are found at www.math.csi.cuny.edu/pmg. If
the GTK libraries are installed (a big if under windows!) then this
will install pmg, and the others:

install.packages("pmg", dep=T)

Installation of the GTK libraries varies. Within windows there is a
self-extracting installer at http://gladewin32.sourceforge.net/ For OS
X and Linux there are various ways. A 2.8 or newer version is needed
for RGtk2. The RGtk2 website (www.ggobi.org/rgtk2) has some extra
info.

This will install gWidgetsrJava (and likely JGR too)

install.packages("gWidgetsrJava", dep=T)

To see if you installed pmg correctly, you can try

library(pmg)

The GUI should pop up.

To test if gWidgets is installed properly, try

library(gWidgets)
glabel("hello world", cont=T)

a window should appear, perhaps after you are  asked to select a toolkit.
