R help - Dec 2002 - (no subject)

Dear R-Help list members,


I started programming in R not very long ago, and I would like to make my
own changes in functions like isoMDS (library MASS), as for example
changing the definition of the stress function. 
Looking at the code of isoMDS, it seems that the function uses precompiled
C code routines. Is there a way to get those routines and include own
changes there, or would I have to write an own, new isoMDS-function?


Thanks a lot for your help!

The C code is part of the sources on CRAN.  If you have precompiled code
you are probably using Windows or MacOS and omitting to tell us.
If you are using Windows, do read the rw-FAQ about installing packages.
