Thanks a lot, FD See ?ordiplot3d and ?ordirgl in package vegan. rda() in that package can be used to perform PCA, which can then be drawn in 3D using the rgl package or the scatterplot3d package, the former allowing dynamic rotation and zooming of the ordination configuration.

Can anyone point me a hint (package) how to draw a 3D plot using the first 3 You might want to have a look at ggobi (http://www.ggobi.org) and rggobi (http://www.ggobi.org/rggobi) which will allow you to look at any number of principle coordinates. (And don't forgot to look at the high ones - interesting structure is often revealed there) Hadley __ 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 and provide commented, minimal, self-contained, reproducible code.
