[BioC] SNP chips

[James MacDonald]

I just tried to make an environment, which was successful. However, I
don't have any .cel files to try read.affybatch. If anybody has a SNP
.cel file or two that they can part with, please let me know.

Conversely, I could send the environment to anybody who wants it.

I worked with Affy SNP chips 4 years ago.  I don't know if they are
just 
the same now, but they were quite similar to the expression chips with

data stored in .cel and .cdf files in a very similar format.  I imagine

that many of the functions in the Affy package could be very quickly 
adapted to SNP chips, if they don't work already.  Has anyone tried to

make a SNP cdf environment and then use read.affybatch?
