lsoda does not solve delay differential equations, which is what you
need to be able to do. A quick search on netlib (netlib.org) turned up
one match for "delay differential equations": ode/ddverk.f, which might
help (though not in R).

Subject: [R] How to solve differential equations
Hi,
I would like to solve a system of coupled ordinary differential equations,
where there is a delay (time lag) term. I would like to use the "lsoda"
function "odesolve" package. However, I am not sure how to specify the
delay term using the syntax allowed by odesolve.
Here is an example
