Examples

## generate two-cluster data
mymu1 = c(0,0,0,1)  # center of class 1
mymu2 = c(-1,0,0,0) # center of class 2

x1 = rvmf(50, mymu1, kappa=15)
x2 = rvmf(50, mymu2, kappa=15)
xx = rbind(x1,x2)

## compute 2d embedding and visualization
mds2d <- sp.mds(xx, ndim=2)
plot(mds2d$embed[,1], mds2d$embed[,2], pch=19)
