Re: help about ReadAffy() erro

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().

Second, use RMAexpress (Google it).

Third, buy RAM.

Best,

Just to add to Jim's remarks...

I found that if you have at least 1GB or RAM, and you are running firefox
with multiple tabs (or any other software that uses lots of RAM), R cannot
do what it wants. If you have just enough ram for what you want to do, try
closing down all other applications lest you run into this error.
