[BioC] Affymetrix cdf-package question

[Tae-Hoon Chung]

Hi, all;

While analyzing Affymetrix data set, when gene-information is necessary 
after probe-level data analysis is performed, Bioconductor looks for a 
related CDF package and if it cannot find it locally, it tries to get 
it from Bioconductor web site and install it. (If this is not correct, 
please let me know.) My question is this. When Bioconductor tries to 
install CDF package, it tries to do it globally, I mean it requires 
some root-level security privilege to install the necessary CDF 
package. Is there any way that this can be done locally, that is make 
Bioconductor install the necessary CDF package in a user's local 
directory and fetch gene-information from it, which will not require 
root-level privilege?
