dear users of the affy package,

we are considering making a change to the pm and mm methods to speed them 
up (roughly 4 times faster). if this is done pm(affybatch) will return the 
exact same matrix as before but with no rownames. i personally never use 
these rownames but i use pm(affybatch) quite often.

to get the same rownames you will have to do something like this:

pms <- pm(affybatch) 
rownames(pms) <- probeNames(affybatch)

if this will affect anybodies code please let me know.
