Re-structuring your exmaple as received [please see to your mailer's formating!] into what I think you may mean: Col1 Col2 1 2 3 4 5 6 7 8 9 10 You haven't stated in what form these two columns are available to you at the point where you want to "merge" them, so I'll give two answers (there may be others, deending on the source of Col1 and Col2). 1. Suppose they are two columns of a matrix M: M c1 c2 [1,] 1 2 [2,] 3 4 [3,] 5 6 [4,] 7 8 [5,] 9 10 Then: as.vector(t(M)) [1] 1 2 3 4 5 6 7 8 9 10 2. Suppose they are available as separate vectors Col1 and Col2: as.vector(rbind(Col1,Col2)) [1] 1 2 3 4 5 6 7 8 9 10 Best wishes, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <[EMAIL PROTECTED]> Fax-to-email: +44 (0)870 094 0861 Date: 20-Aug-07 Time: 12:27:54 ------------------------------ XFMail ------------------------------ ______________________________________________ R-help@stat.math.ethz.ch 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.
