I would like to implement the "Earth Movers Distance" into R and found
the code in C on the following page:


Unfortunately, I don't know much (nearly nothing) about C and how to
call it from R.
As far as I have seen, the calling of the code from R should be rather
straight forward, but there are still several things I don't

Could somebody please help me in calling the code from R?



P.S: if the code works nicely, I would like to either put it into a
package or add it to one.
