[R] Document clustering for R

[Christian Hennig]

If you are able to implement the computation of the distance matrix, you
can use methods such as pam, agnes and hclust, which operate on
dissimilarity matrices of any kind. You may also perform a
multidimensional scaling with isoMDS, sammon or cmdscale and use any
clustering algorithm for n*p data on the outcome.

Best,
Christian
