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.
