[R] How to estimate the parameters of differential equations from data

[Jannik Vindeloev]

Hello list

I have a theoretical differential equation model (two coupled differential
equations) describing the acidification of dairy cultures in milk:

dX/dt = f(H, param)*X
dH/dt = g(param)*dX/dt

pH = -log10(H)

I also have actual data of the same.

I would like to estimate the parameters of the theoretical model from real
data, but don't know how to go about it in R (I'm fairly new to R). Is
there an R-package for this purpose?

Any help from the list is highly appreciated.

Thank you
