Hi Marna, when you use facet there is just one X-axis title and one Y-axis title. As an alternative you can create several plots and put them into one using the package gridExtra.
As for adding text you can use geom_text and extract the x, y coordinates from your data. When I add text, I usually create a separate data.frame which in addition to the text I want to add and the positions also contains indications of the global aesthetic and the facet column Hope this helps Ulrik On Thu, 1 Sep 2016 at 15:48 John Kane <[email protected]> wrote: > Hi Marna, > > Thanks for providing the data and code.
