Why Use R in Computational Biology?
The name “R” refers to the computational environment initially created by Robert Gentleman and Robert Ihaka, similar in nature to the “S” statistical environment developed at Bell Laboratories (http://www.r-project.org/about.html) [1]. It has since been developed and maintained by a strong team of core developers (R-core), who are renowned researchers in computational disciplines. R has gained wide acceptance as a reliable and powerful modern computational environment for statistical computing and visualisation, and is now used in many areas of scientific computation. R is free software, released under the GNU General Public License; this means anyone can see all its source code, and there are no restrictive, costly licensing arrangements. One of the main reasons that computational biologists use R is the Bioconductor project (http://www.bioconductor.org), which is a set of packages for R to analyse genomic data. These packages have, in many cases, been provided by researchers to compl
