[R] Fitting a System of Difference Equations

Hi R friends, I’m interested in fitting data to the following system of difference equations: Change in M = k*(1-M.prev)*(1-F.prev) + R*(1-M.prev)*F.pref Change in F = k*(1-F.prev)*(1-M.prev) + S*(1-F.prev)*M.pref Parameters: k, R, S, are transition rates Variables: M = Proportion of Males
