plot_title_two1: combines two plots together (e.g. employment and GDP)
In aranryan/arlodr:

to get this function to work I needed to modify ggsave using the following line this is because I've used ggplot_gtable, and so the pieces aren't ggplot plot elements, and that's what's expected in ggsave. Based on: http://stackoverflow.com/questions/18406991/saving-a-graph-with-ggsave-after-using-ggplot-build-and-ggplot-gtable this should no longer be necessary, so I've commented it out ggsave <- ggplot2::ggsave; body(ggsave) <- body(ggplot2::ggsave)[-2]
