[BioC] Affy Bugs?

[Rafael A. Irizarry]

sorry for the late response. regarding your bug report about 
write.exprs... i wrote it so that it behaves similar to write.table.
if you look at the help file for write.table you will see that 
the following  does what you want: creates a file that opens correctly on 
microsoft excel.

write.exprs(e,file = "mydata.csv", sep = ",", col.names = NA) 

here,  e is an exprSet. notice i changed your "txt" to "csv"... 
i believe that 
by default, on msft windows, files ending in csv  will automatically be 
opened by excel. also it better describes that this is a comma delimited 
flat file.

hope this helps,
rafael
