#' GAPGOM internal - Miscellaneous functions
#'
#' These functions are misc. functions that are mostly used in applies. They
#' are defined here probably because they are used often.
#'
#' @param x vector of expression values
#' @param args internal arguments, used for target expression datas
#'
#' @section Notes:
#' These functions are internal functions and should not be called by the user.
#'
#' @return output is different on a case-to-case basis
