Add/remove the panel border in a ggplot2 plot

This function provides a simple way to modify the panel border in ggplot2. It doesn't do anything that can't be done just the same with ggplot2::theme(). However, it saves some typing.

panel_border(color = "grey85", size = 1, linetype = 1, remove = FALSE, colour)

Arguments

color, colour

The color of the border.

size

Size. Needs to be twice as large as desired outcome when panel clipping is on (the default).

linetype

Line type.

remove

If TRUE, removes the current panel border.
