Hi All! I got long ago used to R 2.3.1, and yesterday I upgraded to the current vesion (R 2.6.2). And of course I run into a major problem: the exprs2excel command is not functioning any more. I receive following error message after MAS5 normalization: > Myproject.raw<-ReadAffy() > Myproject.mas5<-mas5(Myproject.raw) > exprs2excel(Myproject.mas5, file="Myproject_mas5.csv") Error in function (classes, fdef, mtable) : unable to find an inherited method for function "exprs2excel", for signature "ExpressionSet" In the previous version I don't had this problem. How can I get the data in a CSV file?

I think what you want is write.exprs(Myproject.mas5, file="Myproject_mas5.csv", sep=",") Best, Jim > > Thanks: > Balazs > > > ------------------------- > Bal?zs GY?RFFY MD, PhD > Hungarian Academy of Sciences and Semmelweis University > Research Group for Pediatrics and Nephrology, > Ist Dept of Pediatrics, > B?kay u. 53/54, Budapest, > H-1083 Hungary > Mobile: +36 30 514 2822 > Tel/Fax: +36 1 266 0926 /2772 > Fax: +36 1 3036 077 > Email: zsalab2 at yahoo.com > > > Machen Sie Yahoo! zu Ihrer Startseite.
