Hi Bioconductor gurus:
I am trying to make ExpressionSet files for the analysis of PCR
arrays, to be able to analyze them in LMGene. However, I get the
following error message:
> eSet_xxx <- new("ExpressionSet", exprs = exprs_xxx, phenoData = phenoData_xxx, experimentData = experimentData)
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function
"annotatedDataFrameFrom", for signature "data.frame"
I have done this a gazillion times before without a hitch, and
suddenly I'm not able to do so anymore. If anyone knows what's going
on, I am all ears.
