[R] installing package

[Gitte Brinch Andersen]

Hi

I am trying to install a package (bioconductor) but every time I try to install it I get this message:

source("http://bioconductor.org/biocLite.R")
Warning in install.packages("BiocInstaller", repos = a["BioCsoft", "URL"]) :
  'lib = "C:/Program Files/R/R-3.0.0/library"' is not writable
Error in install.packages("BiocInstaller", repos = a["BioCsoft", "URL"]) : 
  unable to install packages
>     biocLite("methylumi")

I normally use mac computers, but I cannot get the right path for the folders I should use, so now I am trying with a windows platform instead. But now I cannot install one of the packages my pipeline needs.

Can anyone help?

I know it is probably a simple problem, but I have never used R before and don't know how to solve problems in it.

Best
