What's wrong with geom_text?
my.value = 0.65 qplot(1,1)+geom_hline(v=0)+ geom_text(mapping=aes(x=1,y=0),label=paste(my.value),vjust=-1)

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?)
