In Dasonk/future3.0: Imports functions that were introduced in R 3.0

#' Replicate Elements of Vectors and Lists
#' 
#' A simplified version of rep for when you want to repeat
#' an input to a desired length.  Introduced in 3.0.0 - this
#' function has a slight speed advantage compared to rep in
#' 3.0.0 but not here.
#' 
#' @param x: a vector (of any mode including a list) 
#' or a factor or (for rep only) a POSIXct or 
#' POSIXlt or Date object; or an S4 object 
#' containing such an object.
#' 
#' @param length.out non-negative integer.  The 
#' desired length of the output vector.  Other inputs 
#' will be coerced to an integer vector and the first 
#' element taken.  Ignored if NA or invalid.
#' 
#' @seealso \code{\link[base]{rep}}, \code{\link[base]{rep.int}}
#' 
#' @export
