Rightly (but perhaps wrongly) I was trying for a simple method where
the plots just change. If prettyB loaded, the plots just look a little
nicer. If prettyB isn't available, then the plot function works as normal.
So two possible options are:
* registerS3method - I suspect this isn't permitted.
* Don't override plot.default(), but override other methods. E.g.
boxplot.list() and plot.numeric(). But is this going against the
spirit of the law?
