[R-gui] New version of Rpad released

[Short, Tom]

Another release of Rpad is available. Rpad is an interactive, web-based
analysis program. Rpad pages are interactive workbook-type sheets based
on R. Rpad is an analysis package, a web-page designer, and a gui designer
all wrapped in one.

For more information and demonstrations, please see:

Most of the changes in this version are tweaks and bug fixes. The most
notable bug caused Internet Explorer to lock up at times. The tweaks
improve compatibility with R 2.0 and apache2. Rpad works well with R 2.0.
The lazy loading in 2.0 improves startup responsiveness and should reduce
the memory load on the server. Note that the server at www.rpad.org still
uses R 1.9.1; I'm waiting for R 2.0 to make it into Debian's testing
distribution. Key new features in the 2004-11-02 release include:

(*) MULTIPLE-FIGURE PLOTTING -- Many plots can be generated and shown
at once in the browser. For example, you could enter the following to
show all of the graphs in the demo for graphics:

      newgraph(width=6)
      demo(graphics)
      HTMLon()
      showgraph()

(*) EASY GUI GENERATION -- I added two examples for adding GUI elements
for adjusting plot parameters. This is a starting point for automating GUI
generation for entering many parameters.

(*) Rpad & R REFCARD -- I made a 4-page quick reference of common
functions that's based largely on Emmanuel Paradis's excellent "R for
Beginners" (http://cran.r-project.org/doc/contrib/rdebuts_en.pdf).
There's also a reference card just for R. The latex source is also
available if you want to make customized versions of this.

This release also includes an install script for Debian. I'm working
on this in hopes of making a Debian package with the goal of
getting Rpad included on Dirk Eddelbuettel's Quantian livecd.
