== 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
{{{las}}} values are:
0:
always parallel to the axis [default],
1:
always horizontal,
2:
always perpendicular to the axis,
3:
always vertical.
For a general reference, look at the {{{par}}}
