[BioC] Custom CDF Files - howto ?

[Richard Finney]

I have created a custom CDF file.

The purpose is to measure the expression of splice
variations.

I place the file in the same directory as the CEL
files and crank up R and do the usual BIOC
incantation.

Based on a suggestion offered by the brainiacs at
University of Michigan (
http://brainarray.mhri.med.umich.edu/Brainarray/Database/CustomCDF/cdfreadme.htm#How_to_use_the_custom_CDF_file:_
)
I try something like this ...

data<-ReadAffy();
data at cdfName<-"NEW.CDF"

But subsequent data processing calls attempt to
connect to the internet and get a CDF file from there.

Obviously, I missing something.

Anybody got any ideas?

Please add to any "RTFM" responses a specific FM to
read.

Thanks!
