Hi,
I am trying to replicate the data on biogps.com of the Z-score. They
explain the source of how they calculated it. However, I am not familiar
with RGUI and have been struggling to run the following code...
6. Read in the data and preprocess using the default options.
> library(frmaExampleData)
> data(AffyBatchExample)
> object <- frma(AffyBatchExample)
7. Create a gene expression barcode.
> bc <- barcode(object)
I have gotten to the point of data(bcparams).. which runs fine...
However, object <- frma(bcparams) ... I get an error message...
"Error in frma(bcparams) :
object must be of class AffyBatch or ExonFeatureSet"
Please help with this step... as well, I am not interested in the
barcode but the z-score... how would I output this...
Thank you.
