[R] Lyapunov exponent code for time series

[Stephen Ellner]

The lyapunov exponent part of Funfits is semi-available,
but only for Windows. Doug Nychka and I, who wrote that part 
of Funfits, started trying to make it a CRANworthy package but 
never got it done. I've just linked it to my web page 
(www.eeb.cornell.edu/Ellner); follow the Software link on 
that page and get LENNS.zip.
