- Soap film smoothers are included in R package mgcv from version 1.7-21. The code there
is based on sparse matrix methods for solving the defining PDEs and is somewhat faster than the
code here. soap_0.1-5.tar.gz implements soap
film smoothing based on multigrid PDE solution, but is no longer maintained.
You'll need mgcv 1.5-6 or above for this to work. See the
examples in help("soap-package") to get started. The paper describing this is

Solv95 - A delay differential equation solver for Windows
operating systems. This is open source, and comes with examples and
documentation. All you need to use it is a C/C++ compiler: gcc
(which is free) works fine, and links to a suitable port are provided.
This is fairly mature and reasonably well tested (however I've received
reports that the windows interface no longer compiles properly on some platforms).
- mgcv -
an R package (also usable with S-PLUS) for multiple smoothing parameter
selection using GCV for generalized ridge regression problems. Also
includes C source that can be used independent of R or S-PLUS.
DDEfit A Windows package that allows you to fit dynamic models
specified as delay differential equations, differential equations or
difference equations to data (models may be partially specified). The
model is specified by editing a template
file written in C, which is then compiled and linked to the libraries
containing the numerical, statistical and graphical routines required. You
need a C/C++ compiler to use this (gcc works). This package
is more ambitious in scope than the last two, so is more likely to
have some glitches.
posum 2 Mortality estimation
software based on the population surface method. The method is implemented
as an open source R package, but relies on a rather old version: will try
to fix soon.
