he <code>predict</code> (moment forecasts) and <code>simulate</code> (stochastic path simulations) methods. The calculations for these may be carried out in either <strong>R</strong> (default) or for additional speed in <strong>C++</strong> using <code>Rcpp</code>. <!-- in particular using the `RcppXPtrUtils` package for sending **C++** pointers of the model-specific functions (drift, diffusion, observation and jacobians) rather than sending (slow to evaluate) **R** functions. --></p>
