[BioC] BAF and logR for Affymetrix SNP-arrays

[Alla Bulashevska]

Dear Bioconductor users,
I would like to use SOMATICS R script (heterogeneous tissue
analysis) written for the analysis of Illumina SNP-arrays
for my Affymetrix SNP-array data. I need to calculate BAF
(B-allele frequency) and logR estimates which are normally
outputed from Illumina BeadStudio software. My question is,
if there exist an R package which calculates this values
from Affymetrix CEl-files and if this will be valid to use
these values in SOMATICS or other packages written for
Illumina data. 
Thank you in Advance,
Alla Bulashevska
