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

5. 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.
