In idrblab/NOREVA2020: R Package for Assessing Normalization for Metabolomic Data

#' @title Normalization with datasets of multi-class (N>1) metabolomic study.
#' @description This function handles normalizing the multi-class metabolomic
#' data using 168 methods/strategies.
#' @param datatype Input the number of data type.
#' If set 1, the dataset of multi-class (N>1) metabolomic study without QCSs and ISs.
#' If set 2, the dataset of multi-class (N>1) metabolomic study with quality control samples (QCSs).
#' If set 3, the dataset of multi-class (N>1) metabolomic study with dataset with internal standards (ISs).
#' @param fileName Please find the detail information of the file format from those six sample
#' files in the working directory (in github) “idrblab/METNOR/data”
#' @param IS Input the Column of Internal Standards. For example,
#' the replacement of IS to 2,6,9,n indicates that the metabolites in the 2st, 6th, 9th, and nth columns of in
#' your input dataset Input-Dataset.csv should be considered as the ISs or quality control metabolites.
#' If there is only one IS, the column number of this IS should be listed
#' If there are multiple ISs, the column number of all ISs should be listed and
#' separated by comma (,)
#' @param impt Input the name of imputation methods.
#' If set 1, method of column mean imputation.
#' If set 2, method of column median imputation.
#' If set 3, method of half of the minimum positive value.
#' If set 4, method of KNN imputation.
#' @param trsf Input the name of transformation methods.
#' If set 1, method of cube root transformation.
#' If set 2, method of log transformation.
#' If set 3, none transformation method.
#' @param nmal NORMALIZATION METHODS1
