Simulating ODE model for different initial conditions in R<p>I have a model, and I want to generate random initial conditions, run the model, and save the output so that each simulation is a replicate.

<p>Here one of the other approaches, mentioned by @Ben Bolker. Here we use <code>replicate</code> instead of a loop.
