R packages - Aug 2010 - Major update of Deducer, including GSOC funded work

A new version of Deducer (0.4) has been sent to CRAN, and should be  
propagating to all the mirrors in due course. Also, a new plug-in  
package (DeducerExtras) has also been released to CRAN, containing  
additional dialogs and functionality.

I would like to take this opportunity to thank the R community for  
choosing this project for a Google Summer of Code grant, and for the  
support and encouragement. In particular I would like to thank Hadley  
Wickham for mentoring the Plot Builder GUI, and Dirk Eddelbuettel for  
his organization of students and mentors.

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

Provide an intuitive interface so that non-technical users can learn  
and perform analyses without programming getting in their way.
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 possible the GUI should not get in their way if they  
just want to do some programming.
Deducer is designed to be used with the Java based R console JGR,  
though it supports a number of other R environments (e.g. Windows  
RGUI and RTerm).


For those not familiar with Deducer, an online manual is available  
at: http://www.deducer.org/pmwiki/pmwiki.php?n=Main.DeducerManual .

			    -------------   Plot Builder   -------------

The major change to Deducer is the inclusion of a new plotting GUI  
built on the ggplot2 package. This Google Summer of Code project  
provides an easy to use system to make anything from simple  
histograms, to custom publication ready graphics. Feel free to check
