ORIGINAL README :

  This directory contains code, help and examples for CLUS, an S-PLUS
  package for clustering, as described in ``Clustering in an
  Object-Oriented Environment'' by Anja Struyf, Mia Hubert, and Peter
  J. Rousseeuw (Journal of Statistical Software, volume 1).

For historical reasons,
we keep R/README-Splus which has no relevance to the R package.

TODO {see ./TODO-MM for MM's private 'todo' list;  ./DONE-MM for things done}

 3) daisy() for the case of mixed variables should allow
    a weight vector (of length p = #vars) for up- or downweighing variables.
    daisy() really should accept the other methods mva's dist() does _and_
    it should use dist's C API -- but we have no C API for package code, ARRGH!

 4) Eliminate the many Fortran (g77 -Wall) warnings of the form
    >> mona.f:101: warning: `jma' might be used uninitialized in this function

 6) Mona objects describe a hierarchical clustering; they could also inherit
    from twins, and hence have a pltree() method for plotting the
    hierarchical tree.

 8b) Think about "merging" the plot.agnes and plot.diana methods.
