Hello,
I'm using geom_hline to add a minimum line to my plot (representing
the best solution found so far by a search algorithm). I'd like to
annotate this line with it's numerical value to save trying to read it
off the graph, but I can't see a clear way to do this - any ideas?
(Alternatively, if this is against the spirit of the grammar of
graphics, is there a better way to represent the information?)
Cheers,
dave
