[BioC] CDF environment missing for HuGene-1_0-st-v1

[James W. MacDonald]

Hi Roxane,

You don't mention your OS. Are you perhaps using MacOS X 10.5 (or 10.6)? 
If so, you can see that the package binary isn't available for that 
version, which may be the problem you are encountering.

If you are set up to build packages (see here if not: 
http://r.research.att.com/tools/ I believe all you need are the Xcode 
Development tools.), then you can simply do

biocLite("hugene10stv1.r3cdf", type = "source")

Best,

Jim
