[BioC] Problem with read.marrayRaw

[Joyce Gu]

Hi Jean,
I did declare Res and Green channels, I am using the following command

> data196.raw<-read.marrayRaw("cDNA196.csv",sep=",",path="~/...",
+ name.Gf="Ch1 Median",name.Gb="Ch1 B Median",name.Rf="Ch2 
Median",name.Rb="Ch2 B Median")

I still got the follwoing error message
[1] "Reading C:/MicroArray/cDNARawData/FormattedData/cDNA196.csv"
Error in "colnames<-"(`*tmp*`, value = fnames) :
        length of dimnames[2] not equal to array extent
In addition: Warning messages: 
1: number of items read is not a multiple of the number of columns 
2: NAs introduced by coercion 
3: NAs introduced by coercion 
4: NAs introduced by coercion

Thanks
