Change the position of the strip label in ggplot from the top to the bottom?
facet, ggplot2, r, strip
Solution
An answer for those searching in 2016.
As of `ggplot2` 2.0, the switch argument will do this for `facet_grid` or `facet_wrap`:
By default, the labels are displayed on the top and right of the plot. If "x", the top labels will be displayed to the bottom. If "y", the right-hand side labels will be displayed to the left. Can also be set to "both".
ggplot(...) + ... + facet_grid(facets, switch="both")
As of ggplot2 2.2.0,
Strips can now be freely positioned in `facet_wrap()` using the strip.position argument (deprecates `switch`).
Current docs, are still at 2.1, but `strip.position` is documented on the dev docs.
By default, the labels are displayed on the top of the plot. Using strip.position it is possible to place the labels on either of the four sides by setting `strip.position = c("top", "bottom", "left", "right")`
ggplot(...) + ... + facet_wrap(facets, strip.position="right")
Problem
I know this is not quite a data visualization issue, but the boss asked for it, so I need to figure out if it is possible.
