Plot method for trajectories

Description

The plot method for Trajectory objects.

Usage

## S3 method for class 'Trajectory'
plot(
  x,
  add = FALSE,
  draw.start.pt = TRUE,
  start.pt.cex = 0.8,
  start.pt.pch = 16,
  start.pt.col = "black",
  turning.angles = NULL,
  xlim = grDevices::extendrange(x$x),
  ylim = grDevices::extendrange(x$y),
  xlab = ifelse(is.null(TrajGetUnits(x)), "x", sprintf("x (%s)", TrajGetUnits(x))),
  ylab = ifelse(is.null(TrajGetUnits(x)), "y", sprintf("y (%s)", TrajGetUnits(x))),
  ann = graphics::par("ann"),
  axes = TRUE,
  frame.plot = axes,
  asp = 1,
  ...
)

Arguments

x	An object of class "Trajectory", the trajectory to be plotted.
add	If TRUE, the trajectory is added to the current plot.
draw.start.pt	If TRUE, draws a dot at the start point of the trajectory.
start.pt.cex	Scale to apply when drawing the start point dot.
start.pt.pch	Pch (i.e. plot character, symbol or shape) to apply when drawing the start point dot.
start.pt.col	Colour to apply when drawing the start point dot.
turning.angles	If "random" or "directed", draws step turning angles. "directed" assumes errors are relative to the first recorded step angle. "random" assumes errors are relative to the previous step.
xlim, ylim, xlab, ylab, asp, ann, axes, frame.plot	plotting parameters with useful defaults.
...	Additional arguments are passed to both plot and lines.
