	  RSiteSearch("Frechet distance") returned only one hit for me just 
now, and that was for a Frechet distribution, as you mentioned.  Google 
found "www.cs.concordia.ca/cccg/papers/39.pdf", which suggests that 
computing it may not be easy.

	  If you'd like more help from this listserve, I can offer two 

	  1.  If you absolutely need the Frechet distance and you can describe 
an algorithm for computing it but get stuck writing a function for it, 
please submit another question outlining what you've tried and that 
obstacle you've found.

	  2.  Alternatively, you might describe the more general problem you 
are trying to solve, why you thought the Frechet distance might help and 
invite alternative suggestions.

	  Hope this helps.
