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.
