This could be done in various extremely simple ways. In the case of your example, suppose that X is a vector containing only the values 0 and 1. Then -5 + 10*X will give a result which has -5 where X has 0, and +5 where X has 1. Another approach would be on the lines of -5*(X==0) + 5*(X==1) Hoping this helps, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <[EMAIL PROTECTED]> Fax-to-email: +44 (0)870 094 0861 Date: 10-Nov-07 Time: 09:32:41 ------------------------------ XFMail ------------------------------ ______________________________________________ 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.
