Plots an object of class "onearrow".

Keywords: hplot, spatial

Usage

## S3 method for class 'onearrow':
plot(x, \dots,
  add = FALSE, main = "",
  retract = 0.05, headfraction = 0.25, headangle = 12, headnick = 0.1,
  col.head = NA, lwd.head = lwd, lwd = 1, col = 1,
  zap = FALSE, zapfraction = 0.07,
  pch = 1, cex = 1, do.plot = TRUE, do.points = FALSE, show.all = !add)

Arguments

x: Object of class "onearrow" to be plotted. This object is created by the command onearrow.
...: Additional graphics arguments passed to segments to control the appearance of the line.
add: Logical value indicating whether to add graphics to the existing plot (add=TRUE) or to start a new plot (add=FALSE).
main: Main title for the plot.
retract: Fraction of length of arrow to remove at each end.
headfraction: Length of arrow head as a fraction of overall length of arrow.
headangle: Angle (in degrees) between the outer edge of the arrow head and the shaft of the arrow.
headnick: Size of the nick in the trailing edge of the arrow head as a fraction of length of arrow head.
col.head,lwd.head: Colour and line style of the filled arrow head.
col,lwd: Colour and line style of the arrow shaft.
zap: Logical value indicating whether the arrow should include a Z-shaped (lightning-bolt) feature in the middle of the shaft.
zapfraction: Size of Z-shaped deviation as a fraction of total arrow length.
pch,cex: Plot character and character size for the two end points of the arrow, if do.points=TRUE.
do.plot: Logical. Whether to actually perform the plot.
do.points: Logical. Whether to display the two end points of the arrow as well.
show.all: Internal use only.

Details

The argument x should be an object of class "onearrow" created by the command onearrow.

Value

A window (class "owin") enclosing the plotted graphics.

Examples

oa <- onearrow(cells[c(1, 42)])
  plot(oa)
  plot(oa, zap=TRUE, do.points=TRUE, col.head="pink", col="red")
