R is a programming language for statistics. However it may have menu-driven versions maybe available R commander we haven't tried that and another one is pmg GTK maybe here

R_Statistics introduces you to R

R reference cheatsheet, also a file here Media:Matlab-python-xref.pdf‎ that gives equivalent code for doing array operations in MATLAB, Python, and R

Examining your data matrix or object, let's say it's called datos
