[R-gui] Seeking comments/testers for a new GUI

[Ian Fellows]

Hello all,

I have just released the first per-alpha version of a new GUI project to
CRAN, and am seeking some feedback from the community.

The package is called Deducer, and it is designed to be a free easy to use
alternative to proprietary software such as SPSS, and Minitab. It has a menu
system to do common data manipulation and data analysis tasks, and an
excel-like spreadsheet in which to view and edit data frames. The goal of
the project is to two fold.

1. Provide an intuitive interface so that non-technical users can learn and
perform analyses without programming getting in their way.
2. Increase the efficiency of expert R users when performing common tasks by
replacing hundreds of keystrokes with a few mouse clicks. Also, as much as
the GUI should get in their way if they just want to do some programming.

Deducer's dialogs are built on top of the Java based R console JGR. To use
Deducer follow these three steps:

1. Download and install JGR from: http://jgr.markushelbig.org/Download.html
2. Open JGR and at the prompt enter: install.packages("Deducer")
3. Enter: library(Deducer)     ##you should now see Data and Analysis menus


Any comments, suggestions or bug reports are greatly appreciated. 

Thank you,
Ian Fellows

Known issues:
  On some systems, using the "packages & data" menu from within the data
viewer causes the program to hang.
