(2) Sorry, I'm lost. I don't really see how that can be the case.

Are you perhaps `source`-ing an entire file or something and therefore
missing where the error is happening. Or trying to copy a code chunk
from a text editor, and pasting it all into an R session? Or are you
really running each line out at a time and waiting for each result
before you try to run the next line?

You're saying that after you run this line:

##Select the 1st 100 probsets
R> resT7561<-resT[1:100,]
R> resT7561

You get this error:

>> Error in function (classes, fdef, mtable)  :
>>  unable to find an inherited method for function "exprs", for signature
>> "data.frame"

?
