while teaching R, the question came up if it would be possible to add
a picture (saved on the HDD) to a graph (generated by plot()), which
we could not answer.
It might easily kill a clean graph, but: is there a way of doing this,
even one should not do it?
On a similar line of thought: is it possibe to define own symbols so
that they can be used in the plot function with pch=?
