[BioC] how do I add pheno data after making AffyBatch object

[Rafael A. Irizarry]

yes you can. 

first creat a phenodata object using read.phenoData (read the help file
for more info), for example,

pd <- read.phenoData(filename="pheno.txt")

and then simply type

phenoData(abatch) <- pd

-r

here is an example of a pheno.txt file:

            label otherstuff RNA
Empty           0          0   0
NoRNA           1          1   0
NotLabeled      0          1   1
BA_polyGRNA     1          1   1
