sample2: Takes samples in the usual manner

In DDD: Diversity-Dependent Diversification

Takes samples in the usual manner

Description

The standard sample function in R samples from n numbers when x = n. This is unwanted behavior when the size of the vector to sample from changes dynamically. This is corrected in sample2

Usage

sample2(x, size, replace = FALSE, prob = NULL)

Arguments

x	A vector of one or more elements
size	A non-negative integer giving the number of items to choose.
replace	Should sampling be with replacement?
prob	A vector of probability weights for obtaining the elements of the vector being sampled.

Value

sam	A vector of length size that is sampled from x.
