# This example shows how to use purrr to simulate ecological values. The 
# accumulate function in purrr can be quite flexible as it can take lists as 
# entries, and pass extra parameters on to the function. The key feature
# to allow for time-varying parameters here is that the input for the function
# has to include both the present state of the population(s), but also a time
# index, so the function knows what values of the parameters to refer to.
