[BioC] Limma

[James MacDonald]

Assuming your data are in an MAlist (called say, my.malist), you should
be able to do something like

write.table(my.malist$M, "M values.txt", sep="\t", quote=FALSE,
col.names=NA)
write.table(my.malist$A, "A values.txt", sep="\t", quote=FALSE,
col.names=NA)

Note that these are _not_ the normalized cy3 and cy5 data, but the M
and A values. You will have to convert back to normalized intensity
values if that is what you want.

HTH,

Jim

Hi
I am using bioconductor  and limma for analysing some cDNA moicroarray

data, I would like to export the normalized MA data  ( normalized cy3
anb 
cy5 values) as tab delimited text file...Could you please tell how I
could 
do that ?
