Adds curly brackets to plot

curly(
  x,
  y,
  len = 1,
  theta = 0,
  wid,
  shape = 1,
  col = 1,
  lwd = 1,
  lty = 1,
  grid = FALSE,
  npoints = 50,
  text = NULL,
  offset = c(0.05, 0)
)

Arguments

x

center of the x axis of the curly brackets (or start end coordinates (x1,x2))

y

center of the y axis of the curly brackets (or start end coordinates (y1,y2))

len

Length of the curly brackets

theta

angle (in radians) of the curly brackets orientation

wid

Width of the curly brackets

shape

shape (curvature)

col

color (passed to lines/grid.lines)

lwd

line width (passed to lines/grid.lines)

lty

line type (passed to lines/grid.lines)

grid

If TRUE use grid graphics (compatability with ggplot2)

npoints

Number of points used in curves

text

Label

offset

Label offset (x,y)

Examples

if (interactive()) { plot(0,0,type="n",axes=FALSE,xlab="",ylab="") curly(x=c(1,0),y=c(0,1),lwd=2,text="a") curly(x=c(1,0),y=c(0,1),lwd=2,text="b",theta=pi) curly(x=-0.5,y=0,shape=1,theta=pi,text="c") curly(x=0,y=0,shape=1,theta=0,text="d") curly(x=0.5,y=0,len=0.2,theta=pi/2,col="blue",lty=2) curly(x=0.5,y=-0.5,len=0.2,theta=-pi/2,col="red",shape=1e3,text="e") }
