Dear colleague,
I'm trying to perform an analysis of set of mouse microarrays (Affymetrix Mouse Gene 1.0-ST Array Transcriptcluster) using the package puma. I'm quite new to this package so I'm trying to follow the vignette but I'm getting stuck with a very early error that I'm unable to interpret and tackle:
> Data.mmgmos <- mmgmos(Data)
Error in exprs(object)[mmIndex, ] <- value :
NAs are not allowed in subscripted assignments
Following I'm attaching my whole commands' sequence, and sessionInfo, for your convenience

Hi, Georgia.
I realized a few months ago that this GSE (and others like it) existed. I
added a function to GEOquery to grab the GSE data tables. In the case of
GSE3494, there are two of these data tables, so the function will return a
list of two data.frames.
gsedt = getGSEDataTables('GSE3494')
Now, gsedt is a list of length 2 and holds each of the GSE data tables in
the list. You can use getGEOSuppFiles to get the actual raw data. With the
two pieces, it is not difficult to generate an ExpressionSet using the
normal affy/Bioc tools.
Hope that helps.
