[R] How to create own distance measure in cluster ?

[Ricardo Zorzetto Nicoliello Vencio]

Hi everyone,

I want to create my own distance measure, other than 'euclidean' or
'manhatan', to use in cluster pckgs. To do this I think that I need to
change dist(), in mva pckg, or daisy(), in cluster pckg. (or is there a
cleaver way ?)


But this functions are in fact things like: .Fortran( "daisy", ... ) or
.C("dist",...).

I tried unsuccessfully to find source code of .Fortran or .C function to
lear how R calculate dissimilarity matrix and then modify source to add my
own distance metrix.

Could someone help me ? Help me to find .Fortran(...) source or helpe me
with better idea to implement my own distance metrix ?
