Draw an oriented box

Description

Adds an oriented box to an existing plot.

Usage

drawBox2(x, fg = par('fg'), bg = NA, colCtr = NA,
         lty = par('lty'), lwd = par('lwd'), pch = par('pch'),
         cex = par('cex'))

## S3 method for class 'list'
drawBox2(x, fg = par('fg'), bg = NA, colCtr = NA,
         lty = par('lty'), lwd = par('lwd'), pch = par('pch'),
         cex = par('cex'))

## Default S3 method:
drawBox2(x, fg = par('fg'), bg = NA, colCtr = NA,
         lty = par('lty'), lwd = par('lwd'), pch = par('pch'),
         cex = par('cex'))

Arguments

x	either a list with component pts as returned by getMinBBox, or a numerical (4 x 2)-matrix giving the (x,y)-coordinates of the ordered box vertices.
fg	color of the box' rim.
bg	the box' fill color. Set to NA for a fully transparent box.
colCtr	color of the center point. Set to NA to omit.
lty	line type of the box.
lwd	line width of the box.
pch	symbol used for the center of the box.

Examples

xy  <- matrix(round(rnorm(20, 100, 15), 1), ncol=2)
(bb <- getMinBBox(xy))

plot(xy, xlim=range(c(xy[ , 1], bb$pts[ , 1])),
         ylim=range(c(xy[ , 2], bb$pts[ , 2])), asp=1, pch=16)
drawBox2(bb, fg='blue', colCtr='blue', pch=4, cex=2)
