If you look in the Biobase vignette, there is a section that explains
how to make a phenoData object by hand. Basically what you need is a
data.frame containing the phenodata information, and a list
corresponding to the labels you want for the phenoData object.
Alternatively, you can use widgets to make the phenoData object as part
of reading in your cel files.
dat <- ReadAffy(widget=TRUE)

I have a beginners type question. I see that in simpleaffy one tells
bioconductor what the samples represent through having a tab
deliminated covdesc file in the same folder as the .cel files. Other
packages use phenoData which I gather is seen with the pData(eset)
command, how does one make a phenoData file and where is it kept?
