Hi,

I'm a computational biologist at Genome Sciences Centre, Vancouver,  
BC, Canada.  I'm working on Affymetrix custom bacterial ship,  
Prokaryotic_Rhodobacter capsulatus GEP.

I've encountered some problems with the CDF file.  I've copied the  
rcapex1a520469fcdf directory to /Library/Frameworks/R.framework/ 
Versions/2.7/Resources/library.  However, I got an error as follows:
--------------
 > require(rcapex1a520469fcdf)
Loading required package: rcapex1a520469fcdf
Error in library(package, lib.loc = lib.loc, character.only = TRUE,  
logical.return = TRUE,  :
   'rcapex1a520469fcdf' is not a valid package -- installed < 2.0.0?

 > raw.data <- ReadAffy()
 > eset <<- rma(raw.data)
Error in library("rcapex1a520469fcdf", lib.loc = NULL, character.only

   'rcapex1a520469fcdf' is not a valid package -- installed < 2.0.0?

 >library()

------------------
Was the CDF not installed properly?  I was given the cdf file, not the  
tar.gz file; otherwise, I'd have used R CMD INSTALL.

Your feedback is very much appreciated.

Thanks,
Dorothy
