[BioC] program suggestion - weighted averaging of multiple probes

[alison.waller at utoronto.ca]

Hi Everyone,

I have some experience using Limma, for two-colour cDNA arrays,  
however, now we are going to use Agilent arrays with 3 probes per gene.

I would like to use a weighted average algorithm to calculate an  
average for each gene.

Can someone please recommend a bioconductor program which implements  
such an averaging algorithm.  eg. tukey biweight

Thanks,

Alison
