ggplot2: Using gtable to move strip labels to top of panel for facet_grid

Question

I am creating a graphic using facet_grid to facet a categorical variable on the y-axis. I decided not to use facet_wrap because I need space

Answer 1

I was struggling with a similar problem but putting the labels on the bottom. I've used a code adaptation of this answer. And recently found that

ggplot2 ver.2.2.1.0 (http://docs.ggplot2.org/current/facet_grid.html)

~facet_grid(.~variable,switch='x')

option which has worked beautifully for me.
