There appears to be a problem with this function, in particular the C code (qnorm_c). I run out of memory on a WinXP box with 2Gb ram when I try to normalize only 9 (!) affy U-133A chips. I can do 8, but at 9 I get Error: cannot allocate vector of blahblah kb I ran the debugger on normalize.quantiles, and it blows up right after passing the matrix to the C code. R: 1.7.1 Affy 1.3.4 WinXP 2 Gb RAM I don't have this problem (at least with these 9 chips) on the same box running Linux (R 1.7.1, Affy 1.3.4), so maybe it is a Windoze problem? Jim James W.
