Please don't make _your_ nuisance into others'. Do read the posting guide as suggested above. You have not provided any info for anyone to give you any useful advice beyond those you said you received. R is not all things to all people. If you are so annoyed, why not use SAS/awk/sort and so on? [For my own education: How do you read the file into SAS without specifying column names and types?] Andy ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
