Hi everyone,
I am doing a metaMDS in a sqrt() dataset of 24 samples. The NMDS diagram is
ok but when I try to see the Shepard diagram I have this result:
> stressplot(metaMDS3)
Using step-across dissimilarities:
Too long or NA distances: 147 out of 276 (53.3%)
Stepping across 276 dissimilarities...
Connectivity of distance matrix with threshold dissimilarity 1
Data are connected
Do it means that some data exceed the max dissimilarity (1)? Perhaps
because I have some singletons?
Thank you very much for helping,
--
