Hello,
I am pursuing the development of an individual-based model in R but
there is a series of technical issues for which I don't know where to
find information.
I have written R functions before for simple simulations, but this model
will have more complexities and each individual will need to be
evaluated in many aspects at each time step. My major concern is that I
don't know how to make my program more efficient in terms of using
computer memory and computation time.
What is the maximum matrix size that R could handle?
I have read that R could interact with C and that that can be an
"extremely effective mode for numerical computation" (Bates and DebRoy,
DSC 2003 Working Papers). I have looked for papers on HOW TO make R and
C interact but I can not find many references and would appreciate
suggestions.
Would my model benefit from using object oriented programming in terms
of making the procedures go faster in terms of updating matrices after
time steps?
Thank you for your time.
