1.1 Using the R Computing Environment
The R package is a mathematical computer language and a multifaceted computing
environment for statistics and graphics. Although there are several such packages
available, R is one of the best and, unlike almost all others, it is free. It has a
GNU General Public License. All you need to do to use it is to visit the R website
(/) and download the package from there.
Because of its mathematical diversity and its free availability, R has become a
very popular tool for analysing microarrays. It is based on the S language developed
at Bell Laboratories and therefore shares many similarities with the commercial
package S-PLUS.
Although the methods we discuss in this book can be implemented in other
packages, all the plots and ana ... read full excerpt from Statistics for Microarrays: Design, Analysis and Inference ebook
