Hi,
I hope I am not repeating a question which has been posed already.
I am trying to do the following in the most efficient way:
I would like to sample from a finite (large) set of integers n non-
overlapping
intervals, where each interval i has a different, set length L_i
(which is the number
of integers in the interval).
I had the idea to sample recursively on a vector with the already
chosen intervals
discarded but that seems to be too complicated.
It might be ridiculously easy if you sampled on an index of a group of
intervals.
Why not pose the question in the form of example data.frames or other
classes of R objects? Specification of the desired output would be
essential. I think further specification of the sampling strategy
would also help because I am unable to understand what sort of
probability model you are hoping to apply.
Any suggestions on that?
Thanks a lot.
Hadassa
