[R] Setting scales for ggplot2 with facets

[Tom Hiatt]

Hi Sven,

Not sure if you're still having this problem, but I was as well and googled
into your post. I didn't find a great answer either, but the workaround I'm
using is some dummy points or lines with alpha=0 so they don't show up (ie
geom_hline(yintercept=0, alpha=0)). I suppose the same could be added to
your dataset and plotted as another layer.
