[BioC] reading Aglilent 60mer oligo data files into limma

[André Chanderbali]

Dear All,

I'm have data txt files from Agilent's 60mer Arabidopsis slides that 
were created using Agilent's feature extraction software, and am trying 
to read them into limma (using Bioconductor) and have encountered the 
following problem.

I can read in my targets file just fine but with the follow up command:

"RG <- read.maimages(files=targets$FileName, source="agilent"')"

I get the following:

"Error in grep(pattern, x, ignore.case, extended, value, fixed) : 
invalid command"

Does anyone know why this is and how it can be overcome?

Thank you,
