[BioC] help about ReadAffy() erro

[James W. MacDonald]

Hi Melody,

First off, note that a simple search for 'cannot allocate vector' using 
the Gmane search functions on the BioC website would have come up with 
probably hundreds of hits that would have answered this question for you.

Not sure what you are asking here, but there are three things you can do.

First, try justRMA() or justGCRMA().
