R [1] is an open-source expression programming language containing multiple facilities for data manipulation, calculation and is renowned for its graphical capabilities. It is heavily used to conduct statistics, and also increasing number of bioinformatics packages are being developed. It uses the language S, which makes the learning curve rather steep and long.

The bioinformatics packages are grouped under Bioconductor [2]
