I have just checked in a revised version of combine that does produce the
sampleNames of the combined object. These are the column names of the
exprs slot. There are no rowNames, as usual for AffyBatches (if anything
they would be probeNames).

These updates should be available from the "Developmental Packages"
section of the website soon (check for matchprobes version 1.0.2).
