Quantlet: grbox
Description: Generates a boxplot with mean line and median line. Outliers outside the interval [Q_25-3*IQR, Q_75+3*IQR] will be plotted as crosses, outliers outside the interval [Q_25-1.5*IQR, Q_75+1.5*IQR] will be plotted as circles.

Usage: bp = grbox (x {, col})
Input:
x n x 1 vector, data
col scalar, number of color
Output:
bp composed graphical object

Example:
library("stats")                    ; loads the stats library
library("graphic")                  ; loads the graphic library
x=read("popul")[,1]                 ; reads data file and uses first column
b1d=grbox(x, 2)                     ; boxplot of the us cities in blue(col = 4) color
bd1=grrot(b1d,1)                    ; rotation of the plot
axes=graxes((-0.5|1.5)~(min(x)-0.05*(max(x)-min(x))|max(x)),"yticks",quantile(x,(0:2)/2),"origin",7.5,"xticks",0.5,"xtext","US cities","xtextpos",6,"ytextpos",9,"xtextsize",16,"ytextsize",16)
di=createdisplay(1,1)               ; createdisplay "di"
axesoff()
show(di,1,1,bd1,axes)               ; shows boxplot

Result:
shows a boxplot
