[BioC] Affymetrix 250K SNP aCGH

[Djork-Arne Clevert]

Hi Adrian,

call me biased but please check out the cn.farms package, which support
high performance computing and easily process 700 SNP6.0 arrays on a
machine with 2GB RAM.
For further information about the algorithm and its assessment just drop me 
an email or get the paper from 
http://nar.oxfordjournals.org/content/early/2011/04/12/nar.gkr197.abstract

Cheers,
Okko

> I also wonder what if R is not highly suitable for normalization due
