roundrect: adds a rounded rectangular box to a plot

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 [Shape]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)
