sample takes a sample of the specified size from the elements of x either with or without replacement. Unlike base::sample, sample handles data frames in a reasonable manner.

1	sample(x, size, replace = FALSE, prob = NULL)

`x`	an integer, vector, or data frame.
`size`	a non-negative integer giving the number of items to choose.
`replace`	logical indicating whether sampling should be performed with or without replacement.
`prob`	a vector of probability weights for obtaining the elements of the vector being sampled.

If x is a vector, a vector of length size with elements drawn from x. If x is a integer, a vector of length size with elements drawn from 1:x. If x is a data frame, a data frame with size rows, all the columns in x and one additional column indicating the location of the selected rows in x.
