[BioC] simpleaffy error

That error usually indicates that you have not set the working directory
to the directory containing your files.

HTH,

Dear users,

I have created a directory with a white-space delimited file 
describing my samples called "covdesc" as suggested and have all the 
CEL files in the same directory

I have loaded simpleaffy library and tried to read in the data. I get 

an error that has been previously mentioned but couldn t find the 
solution in the Bioconductor Archives. This is what I type and the 
error

> raw.data <- read.affy()
Error in file(file, "r") : unable to open connection
In addition: Warning message: 
cannot open file `./covdesc'

I am working on a Windows 2000 computer
R version 1.9.1
BioC version 1.4

any suggestions?


Thanks in advance

David
