Hi, I'm trying to use metaMDS with a dissimilarity matrix of angles, not Bray-Curtis, and I wanted to know if there is an in-built function to produce a plot of stress values against dimensions, that could be used to determine the 'true' dimension of the solution. The number of objects is only a lowly 8 so any solution higher than 2-dimensional is not likely to be interpretable, according to Kruskal and Wish's book, but this was nevertheless required and will be useful as I gather more data. I don't have much experience with multidimensional scaling, so any advice/reading sources is/are welcome.
