Jeffries-Matusita distance

I believe not, but it would be a function of less than 10 lines, probably 
quicker to write than search for, find _and_ check what you found agrees 
with your definition (and BTW, more than one defn exists for it).

RSiteSearch("Matusita")

A search query has been submitted to http://search.r-project.org
The results page should open in your browser shortly

(in 2.1.0 beta) gave no matches, and it that is pretty comprehensive.

Does anybody know if the Jeffries-Matusita distance is already applied in R
code?
Does it exist in any available package or has been ? I searched CRAN but couldnt
find anything there..
