The above is the MAS5.0 normalized data and I need to read the data in R but getthe following error:

 mydat=read.csv("trans.csv",header=T)
 Error in make.names(col.names, unique = TRUE) :invalid multibyte string at '<ff><

 -- output of sessionInfo(): 

I tried doing the following :

de=read.table(textConnection("                                                                                        ID_REF           GSM133971          GSM133972               GSM133973

str(de)

But when I try doing for the whole dataset I get an error:

de=read.table(textConnection("trans.csv"),header = TRUE,as.is= TRUE,sep = ',')

de

[1] trans.csv
<0 rows> (or 0-length row.names)
