resampleZeroProof is a version that works even if sum of all probabilities passed to sample.int is zero. This causes an error in sample.int.

resample(x, ...)

resampleZeroProof(spreadProbHas0, x, n, prob)

Arguments

x: either a vector of one or more elements from which to choose, or a positive integer. See ‘Details.’
...: Passed to base::sample()
spreadProbHas0: logical. Does spreadProb have any zeros on it.
n: a positive number, the number of items to choose from. See ‘Details.’
prob: a vector of probability weights for obtaining the elements of the vector being sampled.

Intended for internal use only.
