Thank you all.
We must think about implementing these packages. In the meantime, I
should clarify my question: Is there any evidence that doing the dumb
for loop discretisation is any more dangerous in R, than in any other
language? Apparently not?
Best,

have you looked at lsoda{odesolve}?
have you looked at the scripts\CSTR subdirectory in the fda package? it
includes an example worked in both R and Matlab with slightly better
answers in R but with a much longer compute time.

Dear all,
Has anybody tried numerical solving of ODE's and/or transport equations
in R? (Don't ask how we ended up in using R for this job, in the first
place!)
More precisely, does anybody know any technical issue that could make
the work insecure in the sense of propagation of errors? Is the
