[R] Lyapunov exponent?

[Angel Lopez]

Philippe,
I think, it was discussed last month on the list: 
http://tolstoy.newcastle.edu.au/R/help/04/03/0318.html

In summary:

  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.
