Draws rectangles with rounded corners in conjuction with the theme system.

Usage

element_rect_round(
  fill = NULL,
  colour = NULL,
  linewidth = NULL,
  linetype = NULL,
  color = NULL,
  inherit.blank = FALSE,
  radius = unit(0.1, "snpc")
)

Arguments

fill	Fill colour.
colour, color	Line/border colour. Color is an alias for colour.
linewidth	Line/border size in mm.
linetype	Line type. 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.
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.
radius	A unit of length 1 specifying the maximum radius of circles inscribing the corners. If given a numeric, it is converted to a unit object with the "snpc" unit.
x	A single number specifying size relative to parent element.
lineend	Line end Line end style (round, butt, square)
