[R] Multi-sample clustering

[j.logsdon@lancaster.ac.uk]

I am looking for what is described in Mardia, Kent and Bibby as
multi-sample clustering where the point is to establish the clusters of
already-defined groups - actually with different variances (MKB describe
the homogeneous case).  That is, the case where it is the pre-determined
groups (of different sizes) that need to be clustered, not the individual
data.

Having trawled through the R-pages and also an extensive Google search, I
haven't found anything to wet my appetite.

Have I missed anything in the present libraries (quite possible) or can
anyone direct me to (preferably) R code (or perhaps S-Plus) that may help?

TIA
