totally agree!

R: open source statistics package.

R for statistics, biological data manipulations and graphics:

1. Describe basic statistics of your data.
2. Statistical tests can be done with simple, easy to understand commands.
3. Open source packages specific to microarray analysis.
4. R scripting language can further be used to program for more sophisticated tasks.
5. Example:
Data: Affymetrix microarray expression levels (HG-U95A) of seven genes inferred from the average difference values (AD), random picked from Su et al..
amygdala thalamus fetal brain whole brain caudate nucleus testis
gene1 32.47 39.17 32.33 29.37 44.65 84.59
gene2 54.51 64.76 40.52 31.26 50.92 45.76
gene3 12.14 8.78 3.59 5.43 7.22 48.67
gene4 65.95 5.49 28.54 109.90 83.06 304.02
gene5 34.61 43.86 36.54 35.67 36.44 27.65
gene6 134.53 147.83 133.96 33.89 130.17 216.44

hi

where can I get the basic materials on learning R? I can not open this site:http://cyberpostdoc.org/joomla/index.php?/...ent/view/13/26/
I want to learn biostatistics too.
thank you

R has its own homepage: http://www.r-project.org/
There are manuals, a forum, faqs and many working programs etc. Nevertheless for learning statistics I would recommend a course and a good textbook.
