Hello all, I have been using the function ordirgl to plot 3D dynamic ordinations. The ordirgl function works just fine. IN fact, I was even able to write a function that allows me to identify points in the 3D plot: identify.rgl<-function(env_var,ord,dim1,dim2,dim3) { tmp<-select3d(button="left") tmp.keep<-tmp(...

....mds,envfit=vect_data) ordixyplot(data.mds,pch=pts,envfit=vect_data) (my data's not really called data, I thought it might be easier to communicate this way) These display the vectors as arrows, but what I would really like is for the arrows to be labelled, like what comes up automatically in ordirgl or with a 2D ordiplot. I've gone through the help and tried everything I can work out, but I must be missing something important, because nothing's worked so far. I would be happy to use ordixyplot and show a series of 2D plots, but I can't get labels on those arrows either. Any poin...

Hello R experts, I've used metaMDS to run NMDS on some fish abundance data, and am also working on correlating environmental data to the NMDS coordinates. I'm fairly new to metaMDS and NMDS in general, so I have what are probably some very basic questions. My fish abundance data consists of 66 sites for which up to 20 species of fish were identified and counted. I ran metaMDS on this data

...sues/29 ). The main reason was that rgl can cause problems in several platforms and even prevent installing vegan. Indeed, when I tested these functions, they crashed in this Mac laptop. We have now a separate vegan3d package for these functions https://github.com/vegandevs/vegan3d . In addition to ordirgl + friends, rgl.isomap and rgl.renyiaccum it also has oriplot3d package. This package has now the same functionality as these functions had in vegan, and our purpose is to release that concurrently with vegan 2.2-0. I recently suggested to remove these functions from vegan, but we haven't made t...

Hi All, Can anyone point me a hint (package) how to draw a 3D plot using the first 3 components from PCA? Thanks a lot, FD [[alternative HTML version deleted]]
