[BioC] Create a vector of individual probes to remove from a CDF file

[Dana Wohlbach]

Hello,
I am trying to remove individual probes from analysis by using code  
posted by Ariel Chernomoretz and modified by Jenny Drnevich.   I have  
a list of individual probes that I would like to remove in a tab- 
delimited text file (called rejectedprobes) and the file is in my  
working directory.  The columns in the rejectedprobes file correspond  
to and are named exactly as in the CDF file.  However, when I try to  
use RemoveProbes 
(listOutProbes="rejectedprobes",listOutProbeSets=NULL, cleancdf) as  
directed in the original instructions, it reports the error:
Error in get(x, envir, mode, inherits) : variable "rejectedprobesat"  
was not found
I am wondering if anyone can give me some clues as to ways to fix  
this problem.  If you need more information about the problem I'm  
experiencing, please let me know.

Thanks,
Dana
