[BioC] Normalization of expression values

[dorothyc]

Hi,

I'm trying to normalize a table of probe level intensities (pls. see attachment).  Would you recommend a method, which would take only a matrix but not an AffyBatch or object and do quantile normalization, in R/Bioconductor packages.

I came across normalize.quantiles {affy} but got the following errors:
------
> library(affy) 
> normalize.quantiles(intensity.M,copy=TRUE)
Error: could not find function "normalize.quantiles"
------

Thanks,
Dorothy
