#'
#' DEPRECATED Converts several samples \code{x} random variable (daily precipitation values) extracted by populations represented by the columns of \code{data} respectively or \code{sample}
#' to a normally-distributed samples with assinged mean and standard deviation or vice versa in case \code{inverse} is \code{TRUE} using the function \code{\link{normalizeGaussian_prec}}
#'
#'
#' @param x value to be converted
#' @param data a sample of data on which a non-parametric probability distribution is estimated
#' @param cpf cumulative probability distribution. If \code{NULL} (default) is calculated as \code{\link{ecdf}(data)}
#' @param mean mean (expected value) of the normalized random variable. Default is 0.
#' @param sd standard deviation of the normalized random variable. Default is 1.
#' @param inverse logical value. If \code{TRUE} the function works inversely (the opposite way). Default is \code{FALSE}.
#' @param qnull probability of no precipitation occurrence. (It can be a matrix in case \code{sample="monthly"}
#' @param valmin minimum value of precipitation to consider a wet day
# @param step vector of values in which step discontinuities of the cumulative probability function occur. Default is \code{NULL}
# @param prec amplitude of the neighbourhood of the step discontinuities where cumulative probability function is treated as non-continuous.
#' @param type see \code{\link{quantile}}
#'
#' @param extremes logical variable.
#' If \code{TRUE} (default) the probability or frequency is multiplied by \deqn{\frac{N}{N+1}} where \eqn{N} is the length of \code{data}
#' @param sample information about sample or probability distribution. Default is \code{NULL}
#' @param origin_x date corresponding to the first row of \code{x}
#' @param origin_data date corresponding to the first row of \code{data}
