Plot an Arrow

Description

Plots an object of class "onearrow".

Usage

 ## S3 method for class 'onearrow'
plot(x, ...,
  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.
