roundrect: adds a rounded rectangular box to a plot

In shape: Functions for Plotting Graphical Shapes, Colors

Description

adds a rectangular box with rounded left and right edges to a plot

Usage

roundrect(mid, radx, rady, rx = rady, dr = 0.01, 
          col = "white", lcol = "black", lwd = 2, angle = 0, ...)

Arguments

mid	midpoint (x,y) of the box.
radx	horizontal radius of the box.
rady	vertical radius of the box.
rx	radius of rounded part.
dr	size of segments, in radians, to draw the rounded line (decrease for smoother).
col	fill color of the box.
lcol	line color surrounding box.
lwd	line width of line surrounding the box.
angle	rotation angle, degrees.
...	arguments passed to function filledshape.

Details

radx and rady are the horizontal and vertical radiusses of the box; rx is the horizontal radius of the rounded part.

Here horizontal and vertical denote the position BEFORE rotation.

Examples

emptyplot(c(-0.1, 1.1), main = "roundrect")
for (i in 1:10) 
  roundrect(mid = runif(2), col = i, radx = 0.1, rady = 0.05)
for (i in 1:5)
  roundrect(mid = runif(2), col = greycol(20), radx = 0.05,
            rady = 0.05, angle = runif(1)*360)
