I ran:
drop_token1<-function(x) {
return(paste(x[2:length(x)],sep="",collapse="."))
}
for(affdf in 1:length(out)) {
names(out[[affdf]])<-lapply(strsplit(names(out[[affdf]]),"[.]"),drop_token1)
write.csv(out[[affdf]],file=paste("affymetrix",affdf,".txt",sep=""))
}
I got the files out with headers:
10.11.1_.HuEx.1_0.st.v2..CEL
Minus the first two tokens (X0. and Classical.)
I really appreciate you helping me with this. I'd never have figured this out
in a timely manner.

Okay. Got some lunch, I can think about this with both halves of the brain.
drop_token1<-function(x) {
return(paste(x[2:length(x)],sep="",collapse="."))
}
affnames<-c("X0.Classical.10.11.1_.HuEx.1_0.st.v2..CEL",
"X1.Classical.10.11.1_.HuEx.1_0.st.v2..CEL")
affnames.split<-strsplit(affnames,"[.]")
lapply(affnames.split,drop_token1)
[[1]]
[1] "Classical.10.11.1_.HuEx.1_0.st.v2..CEL"
[[2]]
[1] "Classical.10.11.1_.HuEx.1_0.st.v2..CEL"
This what I get with a toy example. So, I think that:
for(affdf in 1:length(out)) {
names(out[[affdf]])<-lapply(strsplit(names(out[[affdf]]),"[.]),drop_token1)
write.csv(out[[affdf]],file=paste("affymetrix",affdf,".txt",sep=""))
}
should work.
