[satimis]

Hi folks,


Any folk has experience on r-Project;
http://www.r-project.org/

Please shed me some light on its main application with examples.

The package is availabl on Ubuntu repo;

$ apt-cache policy r-base-html
r-base-html:
Installed: (none)
Candidate: 2.4.1-1
Version table:
2.4.1-1 0
500 http://us.archive.ubuntu.com feisty/universe Packages


$ apt-cache policy r-doc-pdf
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
http://www.spss.com/
The commercial statistic computing software

PSPP
http://www.gnu.org/software/pspp/
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 PSPP if I have time.


TIA


B.R.
