Computes all possible samples from a given population using simple random sampling
srs(popvalues, n)are values of the population. NAs and Infs are allowed but will be removed from the population.
the sample size
The function srs() returns a matrix containing the possible simple random samples of size n taken from a population of finite values popvalues.
If non-finite values are entered as part of the population, they are removed; and the returned simple random sample computed is based on the remaining finite values.
srs(popvalues = c(5, 8, 3, NA, Inf), n = 2)
#> [,1] [,2]
#> [1,] 5 8
#> [2,] 5 3
#> [3,] 8 3
