[BioC] gammaFitEM()

[Richard C. McEachin]

Hello All,

I'd like to use gammaFitEM(), methylationCall(), and lumiMethyStatus  
in the lumi package to distinguish methylated versus unmethylated  
sites on the IlluminaHumanMethylation27k chip.  I find these functions  
in "Analyze Illumina Infinium methylation microarray data", but  
nowhere else.

Session info et al., below.  Any help?

Thanks, Rich McEachin
