[R] Trellis Plots: translating lattice xyplot() to ggplot()

[Jeff Newmiller]

I don't actually use lattice very much, but I have no difficulty setting up a lattice plot in a knitr/rmarkdown file, and can think of no reason why you might have concluded that knitr does not support lattice.

Sorry, not going to translate your non-reproducible example... please go the extra little effort to dput some example data so we can communicate clearly about your problem. [1]
