Description

Sample a list or vector

Usage

list.sample(.data, size, replace = FALSE, weight = 1, prob = NULL)

Arguments

.data	A list or vector
size	integer. The size of the sample
replace	logical. Should sampling be with replacement?
weight	A lambda expression to determine the weight of each list member, which only takes effect if prob is NULL.
prob	A vector of probability weights for obtaining the elements of the list being sampled.

Examples

x <- list(a = 1, b = c(1,2,3), c = c(2,3,4))
list.sample(x, 2, weight = sum(.))

Example output

$c
[1] 2 3 4

$b
[1] 1 2 3
