R-help, Is there any package/function in R which can perform multi-dimensional scaling? Thank you in advance
As recently discussed on this list, it's useful to search for
functionality using the help.search() function.
help.search("multidimensional scaling")

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 <jarioksa at sun3.oulu.fi>
