[BioC] Error reading cel files using Readaffy() or getGEO()

[Salwa [guest]]

  I have been trying to read cel files from NCBI website and have been having problems.  I was able to read the cel files using getGEO() using R version 2.14.0 but the problem is i need the matchprobe library which only works under R version 2.11.  So i switched to R version 2.11 but I just keep getting the following error using the getGEO() : Error in validObject(.Object) : 
  invalid class "ExpressionSet" object: featureNames differ between assayData and featureData.  So instead i tried using the Readaffy() from the affy() library but i got the following error:  cannot allocate vector of size 470.1.  I tried increasing the memory using the memory.size() but it doesn't work.  I have alot of space on the directory.  If i use the rma, it will get the expressions and perform rma and i don't want that.
 
 
   Any help or any ideas to get one of them working?
