Bioconductor archives previous releases of all Biconductor packages, see: http://bioconductor.org/checkResults To run edgeR 2.4.6 you need to install R 2.14.2 (available from www.r-project.org), and then install edgeR using biocLite() in the usual way. You will automatically get edgeR 2.4.6. In fact, you will get the version of any package that was part of Bioconductor release 2.9. If you want to run edgeR 2.4.6 in parallel with the current release of edgeR, then you need to have two installations of R. Install R 2.14.2 to run Bioconductor 2.9 including edgeR 2.4.6, and install R 2.15.2 (or 2.15.3) to run Bioconductor 2.11 including edgeR 3.0.8.
