lsoda with arbitrary zero thresholds (with psuedo-solution)
...0.0 faster by setting the
derivatives even larger in absolute value. You may run into problems
with the solver when the derivatives are discontinuous functions of the
state variables.
There is a simple and elegant solution in theory, but not (yet)
available in odesolve. soda has a variant called lsodar that returns
whenever a function of the state variables satisfies a given set of
conditions (in your case, you could tell lsodar to return whenever any
state variable drops below 0.4). Once the call to lsodar returns, you'd
then reset all the state variables that were < 0.4 to 0, and restar...

Ordinary differential equations in R?
Is there any R code available for solving ODE's? I am considering building
an interface to ODEPACK, but don't want to duplicate any existing effort.

Hi Bill and everybody,
if one installs R >= 3.4.2 from any source, then some Debian packages
will be broken. The change of r-api virtual

A Hodgkin Huxley Model
Hi All
It has been suggested to me that the folks in this list might be able to
help me out of my misery.
As part of my learning curve to building a rather detailed model of a small
neurone complex I am implementing some existing models in R.
For the moment I want to implement the Izhikevich model as described in his
2003 paper. The equations are as follows:
v' = 0.04v^2 + 5v + 140 - u - I
