Have you tried 'biplot' and found it unsatisfactory for your needs? biplot(pr) Alternatively, you can do it by hand: plot(pr$loadings, type="n") text(pr$loadings, rownames(pr$loadings), xpd=TRUE) abline(h=0); abline(v=0) If you really want to have Axis 2 as horizontal, then you must replace all pr$loadings pieces with pr$loadings[,2:1]. cheers, jari oksanen -- Jari Oksanen <[EMAIL PROTECTED]> ______________________________________________ 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
