Grobs don't render in Rmarkdown #12

The individual pieces that make up a classifierplot object render fine when you add them in an Rmd chunk, but when you include a the actual classifierplots function, it just prints out the message.

This works

density_plot(test_dat$Outcome, 
                        test_dat$PredEns)

This does not

grobEns <- classifierplots(test_dat$Outcome,
                        test_dat$PredEns) 
grobEns

And neither does this

gridExtra::grid.arrange(grobEns, 
                                top=textGrob("Ensemble model",
                      gp=gpar(fontsize=16,font=1)))

Try grid::grid.draw(grobEns). I'm not really sure why the gTable objects act differently than grobs when you call print on them, they inherit from grob. It's caused problems for other users of arrangeGrob as well. I'm not sure what the best way to fit it is. Perhaps returning a custom class with print that calls grid.draw.
