Examples

## load the data
data(spdat.orbital)

## visualize using multidimensional scaling
dmat = sp.pdist(spdat.orbital)
mds2 = DAS::cmds(dmat, ndim=2)

x = mds2$embed[,1]
y = mds2$embed[,2]

plot(x, y, pch=19, main="orbital normal vectors",
     xlim=c(min(x)-0.05,max(x)+0.05), ylim=c(min(y)-0.05,max(y)+0.05))
