Plotting metaMDS results: How do I get a horizontal plot with a one-dimensional MDS?
I'm making a one-dimensional rescaling using the metaMDS function from the vegan package as follows:
mydata <- data.frame(X = sample(1:50), Y = sample(1:50), Z = sample(1:50))
mds <- metaMDS(mydata, distance="euclidian", autotransform=FALSE,…
