element_roundrect: round rectangle borders and backgrounds

Description

round rectangle borders and backgrounds

Usage

element_roundrect(
  fill = NULL,
  colour = NULL,
  linewidth = NULL,
  linetype = NULL,
  color = NULL,
  r = grid::unit(0.1, "snpc"),
  inherit.blank = FALSE
)

Arguments

fill

Fill colour. fill_alpha() can be used to set the transparency of the fill.

colour, color

Line/border colour. Color is an alias for colour. alpha() can be used to set the transparency of the colour.

linewidth

Line/border size in mm

linetype

Line type for lines and borders respectively. An integer (0:8), a name (blank, solid, dashed, dotted, dotdash, longdash, twodash), or a string with an even number (up to eight) of hexadecimal digits which give the lengths in consecutive positions in the string.

r

the radius of the rounded corners, a unit object, default is unit(0.1, 'snpc').

inherit.blank

Should this element inherit the existence of an element_blank among its parents? If TRUE the existence of a blank element among its parents will cause this element to be blank as well. If FALSE any blank parent element will be ignored when calculating final element state.

Examples

Run this code
library(ggplot2)
p <- ggplot(mpg, aes(displ, cty)) + geom_point()
p <- p + facet_grid(cols = vars(cyl))
p <- p + theme(strip.background=element_roundrect(fill="grey40", color=NA, r=0.15))
p
p2 <- ggplot(mtcars, aes(mpg, disp, color=factor(cyl), size=cyl)) + 
      geom_point()
p2 + theme(legend.background=element_roundrect(color="#808080", linetype=2))
