This is a copy of the same function from rpexp from package msm. Copied here to reduce dependencies.

rpexp(n = 1, rate = 1, t = 0)

Arguments

n

number of observations. If length(n) > 1, the length is taken to be the number required.

rate

vector of rates.

t

vector of the same length as rate, giving the times at which the rate changes. The first element of t should be 0, and t should be in increasing order.
