Any folk has experience on r-Project;
The R Project for Statistical Computing

$ apt-cache policy r-doc-pdf

Code:

r-doc-pdf:
  Installed: (none)
  Candidate: 2.4.1-1
  Version table:
     2.4.1-1 0
        500 http://us.archive.ubuntu.com feisty/universe Packages

I have been googling a while, Not much information discovered.


What is R?
Introduction to R
has some explanation there on the application of r-project.


What is the difference in application amongst;

SPSS
SPSS, Data Mining, Statistical Analysis Software, Predictive Analysis, Predictive Analytics, Decision Support Systems
The commercial statistic computing software

PSPP
PSPP - GNU Project - Free Software Foundation (FSF)
The Open Source statistic computing software

and

R-Project
???


I know the former 2. SPSS is very expensive. PSPP is free to use. I want to test SPSS if I have time.


TIA


B.R.
