Description

Sample integer number from given continuous vector of line lengths and probabilities, with total n

Usage

n_sample_length(n, l_lengths, weights)

Arguments

n

Sum of integer values returned

l_lengths

Numeric vector of line lengths

weights

Relative probabilities of samples on lines

Examples

# NOT RUN {
n = 10
l_lengths = 1:5
weights = 9:5
(res = n_sample_length(n, l_lengths, weights))
sum(res)
n = 100
l_lengths = c(12, 22, 15, 14)
weights = c(38, 10, 44, 34)
(res = n_sample_length(n, l_lengths, weights))
sum(res)
