[BioC] bioconductor help

[cxd55 at cwru.edu]

Dear there:

I'm trying to install the bioconductor packages into R in Windows. 

1. I downloaded the packages and the getBioC.R into the libary folder of R.
2. Open getBioC.R.
3. getBioC(lib="exprs")

The error message is:
Error in testRversion(descfile) : This package has not been installed properly
 See the Note in ?library

Could you please help me on solving this? Thanks.
