add.trajectories: Plot Function for RRPP

In RRPP: Linear Model Evaluation with Randomized Residuals in a Permutation Procedure

Plot Function for RRPP

Description

Function adds trajectories to a principal component plot

Usage

add.trajectories(
  TP,
  traj.pch = 21,
  traj.col = 1,
  traj.lty = 1,
  traj.lwd = 1,
  traj.cex = 1.5,
  traj.bg = 1,
  start.bg = 3,
  end.bg = 2
)

Arguments

TP	plot object (from plot.trajectory.analysis)
traj.pch	Plotting "character" for trajectory points. Can be a single value or vector of length equal to the number of trajectories. See par and its description for pch.
traj.col	The color of trajectory lines. Can be a single value or vector of length equal to the number of trajectories. See par and its description for col.
traj.lty	Trajectory line type. Can be a single value or vector of length equal to the number of trajectories. See par and its description for lty.
traj.lwd	Trajectory line width. Can be a single value or vector of length equal to the number of trajectories. See par and its description for lwd.
traj.cex	Trajectory point character expansion. Can be a single value or vector of length equal to the number of trajectories. See par and its description for cex.
traj.bg	Trajectory point background. Can be a single value or vector of length equal to the number of trajectories. See par and its description for bg.
start.bg	Trajectory point background, just the start points. Can be a single value or vector of length equal to the number of trajectories. See par and its description for bg. Green start points are the default.
end.bg	Trajectory point background, just the end points. Can be a single value or vector of length equal to the number of trajectories. See par and its description for bg. Red end points are the default.

Details

The function adds trajectories to a plot made by plot.trajectory.analysis. This function has a restricted set of plot parameters based on the number of trajectories to be added to the plot.
