#' Sample sizes for k-fold cross-validation

#' Compute sample sizes for \eqn{k}-fold cross-validation.
#'
#' If N/k is an integer, the sample sizes are k `N/k's (N/k, N/k, ...),
#' otherwise the remainder will be allocated to each group as `uniformly' as
#' possible, and at last these sample sizes will be permuted randomly.
#' @param k number of groups.
#' @param N total sample size.
#' @return A vector of length \code{k} containing \eqn{k} sample sizes.
