#' Chunked
#'
#' R is a great tool, but processing large text files with data is cumbersome.
#' \code{chunked} helps you to process large text files with dplyr while loading
#' only a part of the data in memory. It builds on the execellent R package LaF
#' Processing commands are writing in dplyr syntax, and \code{chunked}
#' (using \code{LaF})
#' will take care that chunk by chunk is processed, taking far less memory
#' than otherwise. \code{chunked} is useful for selecting columns, mutating columns
#' and filtering rows. It can be used in data pre-processing.

#' @section Implemented dplyr verbs:
#'
#' \itemize{
#' \item filter
#' \item select
#' \item rename
#' \item mutate
#' \item transmute
#' \item do
#' \item left_join
#' \item inner_join
#' \item anti_join
#' \item semi_join
#' \item tbl_vars
#' \item collect
#' }
#'
#' filter, select, do, left_join, inner_join
#'
#' @section Not implemented:
#'
#' The following operators are not implemented because data in \code{chunked} is processed
#' chunkwise, so these are not available.
#' \itemize{
#' \item full_join
#' \item right_join
#' \item group_by
#' \item arrange
#' \item tail
#' }
