Random Samples and Permutations
Sample
takes a sample of the specified size from the elements of x using either with or without replacement. The function does the same as the base::sample() and offers additionally an interface for data frames.
Sample(x, size, replace = FALSE, prob = NULL)

size |
a positive number, the number of items to choose from. |
replace |
a non-negative integer giving the number of items to choose. |
