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")
