I am new to the bioconductor and just installed the R 1.7.1 and Bioconductor
on my WinXP machine. I followed the instruction from chris bye's A
Biologist's Guide to using Bioconductor. Everything was fine until I
started to export the normalized data. My test project is test.raw. I did
load the Biobase, marrayInput, marrayNorm, marrayplot packages. The
following is what I copied from R section:
> a <- "a"
> b <- "b"
> test.var <- cbind("a","b")
> test.phe <- new("phenoData", varLabels=test.var)
Error in validObject(.Object) : Invalid "phenoData" object: Invalid object
for slot "varLabels" in class "phenoData": got class "matrix", should be or
extend class "list"
Thanks a lot for your help,
