#' @title To normalize weight values.
#' @description To explain how to normalize weight values if \code{normalize} = TRUE.
#' @param normalize is a boolean value.
#' @param weight is a numeric vector.
#' @param data is a data.frame.
#' @details This function allows users to normalize weights.
#' @details If there is not any weight, the function will create a numeric vector of "1".
#' @details If normalize = TRUE, the function will make every weight value as a "[0:1]" value.
#' @details If normalize = FALSE, the function will not make any changes, weights will be the same.
