== Hacking Boxplots ==

Usually the big nuisance with boxplots is accomodating the labels, which are usually too long.
I suggest to keep the boxplots vertical, turn all the labels to perpendicular to axis, and increase the outer margin on the x-labels side.

{{{
x11 ()
par (omd = c (0, 1, 0.1, 1))
boxplot (<#...>, names = <#x_labels>, las = 2)
}}}

~+{{{omd}}}+~ parameters are: 
 * width (parallel to x axis), left side
 * width (parallel to x axis), right side
 * height (parallel to y axis), bottom
 * height (parallel to y axis), top<<BR>>
~+{{{las}}}+~ values are:
 * 0: always parallel to the axis [default],
 * 1: always horizontal,
 * 2: always perpendicular to the axis,
 * 3: always vertical.<<BR>>
For a general reference, look at the ~+{{{par}}}+~ help page.
