I opened Rstudio and typed source ("http://bioconductor.org/biocLite.R") in console part but says that
A new version of Bioconductor is available after installing the most recent
version of R; see http://bioconductor.org/install

i have already installed R 3.2.0 and
2.15.0, and when i typed biocLite() it said that:
Using Bioconductor version 2.11 (BiocInstaller 1.8.3), R version 2.15.
