Q:

there is no package called 'BiocInstaller'

Whenever I try to install a new package I'm getting this error:
source("http://bioconductor.org/biocLite.R")  
Warning in install.packages :  
  package ‘BiocInstaller’ is not available (for R version 3.0.2 RC)

Error in library(BiocInstaller) :

A:

Install R-3.0.2 (not RC).
Try starting R as follows: R --vanilla
See if you are pointing to a weird mirror. What is the output of getOption("repos")?
Try this: install.packages("BiocInstaller", repos="http://bioconductor.org/packages/2.13/bioc")
