[BioC] How do I make exprSet?

[Hao Liu]

Dear All:

I have a txt file with MAS5 read outs of 201 133A chips, I did it in
windows. I have read it into R and I just wonder how do I make an exprset
from it. (my MAS5 file only contains the signal intensity information, with
probe_sets the leftest column, one sample per column across the whole file).

I tried using new("exprSet",exprs=myobject,phenoData=***). It won't work.

Thanks for your help 

Hao
