Is there any graphical frontend/secondary programm (freely availible for Windowsor Linux) which can be used with R to display the results of a principle component analysis in 3D space (rotatable!?)? It works with Spotfire, but is there any freely or cheaply availible programm? -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

But take a look at biplot in the mva package, which produces VERY interesting plots in _two_ dimensions, and the xgobi package, which produces 3D plots that can be rotated (as I recall - I find these too mind-boggling to deal with, so I don't use it anymore). Perhaps you can make a "triplot" function. For data with more than 2 dimensions, I find "matplot" (in the base package) to be more useful than xgobi (at least for my small brain, which has trouble visualizing in 3D). I haven't thought about how to use this to display principal components, but I'm sure there is a way (with loadings()). -- Jonathan Baron, Professor of Psychology, University of Pennsylvania Home page: http://www.sas.upenn.edu/~baron -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

I think that xgobi (or maybe ggobi) would fit the bill. ---Mike> Is there any graphical frontend/secondary programm (freely availible for > Windowsor Linux) which can be used with R to display the results of a > principle component analysis in 3D space (rotatable!?)?
