Sample a vector

Description

Return a sample from a vector within a grouping variable if specified.

Usage

resample(x, size = NULL, replace = FALSE, prob = NULL, by = NULL)

Arguments

x	numeric vector
size	the number of items to sample within each group, as a positive number or a vector of numbers equal in length to the number of groups. If NULL, the sampling is stratified by group in the original group sizes.
replace	if TRUE, sample with replacement
prob	a vector of probability weights for values in x
by	a grouping vector equal in length to length(x)

Value

x resampled within groups

Examples

set.seed(100)
grvec <- c(rep("a", 3), rep("b", 4), rep("c", 3))
quanteda:::resample(1:10, replace = FALSE, by = grvec)
quanteda:::resample(1:10, replace = TRUE, by = grvec)
quanteda:::resample(1:10, size = 2, replace = TRUE, by = grvec)
quanteda:::resample(1:10, size = c(1, 1, 3), replace = TRUE, by = grvec)
