[BioC] Error wile reading .CEL files

[Tapan Mehta]

Hello,

I am trying to read some .CEL files using the
ReadAffy() function of the Affy library. I am getting
the following error:

Data1<-ReadAffy()
Error in "intensity<-"(*tmp*, value =
c(intensity(cel))) : 
        couldn't find function "exprs<-"

Please can somebody help me understand this error. Is
there a way (some documentation
available )by which I can undertand these errors
myself.

Thanking you,

Tapan Mehta
