Ripley's MASS package has isoMDS for non-metric multidimensional scaling. Moreover, the same package has function sammon for another variant. Some people regard SOM as a "crude form of" multidimensional scalling, and that is -- surprise -- in MASS, too (but there are other implementations). Vasic R (or its stats component) has principal co-ordinates analysis, a.k.a. as metric multidimensional scaling. Finally, R has a utility help.search which would show you most of these and something else, too (perhaps xgvis in the xgobi, if that's installed in your system). Try help.search("multidimensional scaling"). cheers, jari oksane -- Jari Oksanen <[EMAIL PROTECTED]> ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
