Hi R experts, I'm looking for some help with plotting vectors from envfit in vegan, onto a 3d plot using ordiplot3d. So far I have data.mds <- metaMDS(data, k=3,trace = FALSE) vect_data<-envfit(data.mds,vegdata[,3:21],choices=1:3,permu=9999) ordiplot3d(data.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 communicat...

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]]

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
