3\title{Utility Returning x-Coordinates of Boxplot}
4\description{
5  Return the x-coordinates in an \sQuote{n-way} side-by-side boxplot.
6  This is an auxiliary function and exists mainly for backcompatibility
7  with S-plus.

9\usage{
10u.boxplot.x(n, j = 1:n, fullrange = 100)
11}
12\arguments{
13  \item{n}{number of boxplots.}
14  \item{j}{indices of boxplots.}
15  \item{fullrange}{x-coords as 'uniform' in \eqn{[0,fullrange]};
16    (f.=100, corresponds to Splus 3.x (x = 1,2)).}
17}
18\value{
19  a numeric vector of length \code{n}, with values inside \eqn{(0,M)} where
20  \eqn{M = } \code{fullrange}.
