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

• ~Describe the value returned If it is a LIST, use
• comp1
  Description of 'comp1'
• comp2
  Description of 'comp2'
• ...

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.

## The function is currently defined as

  {
    if(length(x)==1)
      {
        if(n==1)
          x
        else
          stop("Requested sample of size ", n, "from list of length 1")
      }
    else
      sample(x, n, ...)
  }
