draw: Randomly draw rows or elements from an object

In Thie1e/convenience: A small collection of diverse functions for more convenient working in R

Description

Randomly draw n rows/elements from an object. Can be useful as an alternative to head(), tail() or ht(). May also be used to quickly draw random samples. Works with tibbles, too, but will return a data.frame in that case.

Usage

draw(x, n = 10L, replace = F)

Arguments

x	An object
n	Single positive integer. The number of rows/elements to be randomly drawn.
replace	If TRUE draw with replacement. Default FALSE

Examples

set.seed(4321)
draw(iris, 6L)
