[BioC] problem with mva.pairs

[Rafael A. Irizarry]

the problem is mva.pairs runs a loess for each pair which can be very time 
consuming in R. if this is happening i would recommend making your own 
mva.pairs... also, if any user out there has something better than the 
current implementation of mva.pairs, please contact me offline to discuss 
the possibility of including it in the affy package.
