Hi all ,

I have one query.

i have list of some  .cel files. in my program i have to mention the path of
these .cel files

part of my program is,

rna.data<-exprs(justRMA(filenames=file.names, celfile.path=*datadir*,
sampleNames=sample.names, phenoData=pheno.data,
cdfname=cleancdfname(hg18_Affymetrix U133A)))


in the place of "datadir" i have to mention the character string of the
directory of these .cel files. I don't know how to give the path for all
these files.

i set the path as given below,


> rna.data<-exprs(justRMA(filenames=file.names, celfile.path="*D:/MONO1.CEL"
"D:/MONO2.CEL" "D:/MONO3.CEL" "D:/MACRO1.CEL" "D:/MACRO2.CEL"
"D:/MACRO3.CEL"*,sampleNames=sample.names, phenoData=pheno.data,
cdfname=cleancdfname(hg18_Affymetrix U133A)))


it shows this error,

Error: unexpected string constant in
"rna.data<-exprs(justRMA(filenames=file.names, celfile.path="D:/MONO1"
"D:/MONO2""


could u please help me in this case.


Thanks in advance.


with regards,

S.Mahalakshmi
