[R-pkgs] Deducer 0.1 : An intuitive cross-platform data analysis GUI

[Ian Fellows]

Deducer 0.1 has been released to CRAN

Deducer is designed to be a free, easy to use, alternative to proprietary
software such as SPSS, JMP, 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 possible the GUI should not 
         get in their way if they just want to do some programming. 

Deducer is integrated into the Windows RGui, and the cross-platform Java
console JGR, and is also usable and accessible from the command line.
