#' cuts continuous variable into quantiles
#'
#' Takes an array of values and assign Quantiles to each one.
#' @param values array of values. The values must be able to rank.
#' @param n number of Quantiles to make the assignment. Takes n=100 by default to assign a percentile to every value.
#' @usage toQuantiles(values,n)
#' @return It returns a List of factors with the percentile of cut of each Quantile.
