It's difficult to help you without an example of your code. I created a very simple example of a data frame with 1,500 columns and had no difficulty saving it to a csv file and viewing the file with both a text editor and with MS Excel (2007) for Windows. df <- data.frame(matrix(1:3000, nrow=2)) write.csv(df, "C:\\junk.csv", quote=FALSE) You may also want to investigate the write.matrix() function in the MASS package. ?write.matrix Jean [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
