Dear all,

I am trying to use oligo to analyze 75 Affy SNP6.0 chips. I have installed
BufferedMatrix, but when I do:

> library(oligo)
> filenames<-dir(pattern="CEL$")
> rawData <- read.celfiles(filenames)
> preProcessedData <- snprma(rawData)

It gave me an error message "Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function "subBufferedMatrix", for
signature "matrix".

What could be wrong?

Thanks,
Ashley Lin
