Hi
 
Does anyone know how to convert the binary data in an affymetrix .CEL file via data.frame or any other way?  The way i normally convert to a data frame doesn't seem to work here.
 
I was to see the raw data from my arrays, but not the grouped probeset data.  
 
I trawled the net, tried numerous commands and i dont think the Affymetirix Expression Console Software does it for the raw data.
 
Alternatively, how can i log2 the .CEL file data.  I want to present it as a heatmap.
 
Cheers!
