#' @title Normalize a vector based on specified minimum and maximum values
#' @description This function normalizes a vector based on specified minimum
#'              and maximum values. If the minimum and maximum values are not
#'              specified, the function will use the minimum and maximum values
#'              of the vector.
#' @param x numeric vector
#' @param min minimum value
#' @param max maximum value

#' @return normalized numeric vector
