plotmatrix(d[,3:6]) I would like to either have a colour or more preferably a shape to correspond to Site this is what I have tried (along with many other combinations) plotmatrix(nmds.bug[,3:6])+scale_shape(nmds.bug, shape=Site, pch=1:12) thanks -- Stephen Sefick Research Scientist Southeastern Natural Sciences Academy Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods. We are mammals, and have not exhausted the annoying little problems of being mammals. -K.
