resample: Consistent Random Samples and Permutations

Description

resample takes a sample of the specified size from the elements of x using either with or without replacement.

Usage

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

Arguments

x

A numeric, complex, character or logical vector from which to choose.

size

Non-negative integer giving the number of items to choose.

replace

Should sampling be with replacement?

prob

A vector of probability weights for obtaining the elements of the vector being sampled.

Value

Vector of the same length as the input, with the elements permuted.

Details

resample differs from the S/R sample function in resample always considers x to be a vector of elements to select from, while sample treats a vector of length one as a special case and samples from 1:x. Otherwise, the functions have identical behavior.

Examples

# NOT RUN {
## sample behavior differs if first argument is scalar vs vector
sample( c(10) )
sample( c(10,10) )

## resample has the consistent behavior for both cases
resample( c(10) )
resample( c(10,10) )

# }
