Bioconductor with R Language Environement

Bioconductor (http://www.bioconductor.org) is an open source project for the analysis and comprehension of genomic data and developed by the Fred Hutchinson Cancer Research Center and various US & international institutions. Bioconductor is based on the R programming language. There are two releases of Bioconductor every year (they appear shortly after the corresponding R release). At any one time there is a release version, which corresponds to the released version of R, and a development version, which corresponds to the development version of R. Most users will find the release version appropriate for their needs. In addition there are a large number of meta-data packages available. They are mainly, but not solely oriented towards different types of micro arrays.
