d is allowed to be an object of class dist or a dissimilarity matrix.
The answer to your question depends on what your "original matrix" is. If
it is something on which you can compute a distance by dist(), you're
right, at least if dist() delivers the distance you are interested in.
> 2) clustering is the clusters vector as result of one of the many clustering
The help page tells you what clustering can be. So it could be the
clustering/partition vector of a clustering method or it could be something
else. Note that cluster.stats doesn't depend on any particular clustering
method. It computes the statistics regardless of where the clustering
vector comes from.
