Consistent Random Samples and Permutations
resample takes a sample of the specified size from the
elements of x using either with or without replacement.
resample(x, size, replace = FALSE, prob = NULL)
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. |
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.
Vector of the same length as the input, with the elements permuted.

## 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) )
