[R] elliptic functions

I'm thinking of putting together some R functionality (maybe a package)
of elliptic functions. An elliptic function is one that is doubly
periodic on the
complex plane and I think they are cool.
One objective of mine is to reproduce Abramowitz and Stegun's
beautiful diagram on
p643 (figure 18.5).
The gsl package does sn, cn, dn et seq, but before I put a huge amount
effort in, has anyone else coded up any related material?
I'd be interested to hear if anyone has anything on Weierstrass's P
function (in particular,
computing omega1 and omega2 from general g2 and g3) and his
sigma functions. Jacobi's theta functions would be good too.
