I am using the deSolve package successfully and I think it is probably your best option if you want to do things in R. The most widespread solver in C++ is the Sundials Suite as far as I know: https://computation.llnl.gov/casc/sundials/main.html I think someone starting writing an interface to R, but it only covers the really basic functions.
