Hi,
I have two vectors as follows:
popd = vector(mode='numeric', 100)
popr = vector(mode='numeric', 100)
These represent the initial distribution within 2 populations.
I want to define these e.g.
popd[]=0.01
popr[]=0.01
These populations will then transform according to the following...
I'm trying to have R go through a loop within ID groups, and within each group:

I would like to split this vector into lengths of 17500 each, and apply the...
