[R-sig-eco] Barton-David statistic implemented in R

[Phil Novack-Gottshall]

Hi all,

I was wondering whether anyone has implemented the Barton-David 
statistics (sensu Simberloff and Boecklen 1981) as R functions.  I've 
searched the various R libraries and help forums, to no avail.  It's 
fairly easy to write new functions for this, but didn't want to 
re-invent the wheel if someone's already done it.

Barton, D. E., and F. N. David. 1956. Some notes on ordered random 
intervals. Journal of the Royal Statistical Society. Series B 
(Methodological) 18(1):79-94.
Simberloff, D., and W. Boecklen. 1981. Santa Rosalia reconsidered: size 
ratios and competition. Evolution 35(6):1206-1228.

Thanks,
Phil
