Construct a base tic-tac-toe plot for presenting predator-prey PSD values.

Description

Construct a base tic-tac-toe plot for presenting predator-prey PSD values. Predator-prey PSD values are added with plotCI from plotrix.

Usage

tictactoe(
  predobj = c(30, 70),
  preyobj = c(30, 70),
  predlab = "Predator PSD",
  preylab = "Prey PSD",
  obj.col = "black",
  obj.trans = 0.2,
  bnd.col = "black",
  bnd.lwd = 1,
  bnd.lty = 2
)

Arguments

predobj

A vector of length 2 that contains the target objective range for the predator.

preyobj

A vector of length 2 that contains the target objective range for the prey.

predlab

A string representing a label for the x-axis.

preylab

A string representing a label for the y-axis.

obj.col

A string designating a color to which the target objective regions should be shaded.

obj.trans

A numeric (decimal) that indicates the level of transparency for marking the target objective regions.

bnd.col

A string that indicates a color for the boundaries of the target objective regions.

bnd.lwd

A numeric that indicates the line width for the boundaries of the target objective regions.

bnd.lty

A numeric that indicates the line type for the boundaries of the target objective regions.

Details

This function simply creates a base tic-tac-toe plot. Observed values, with confidence intervals, are added to this plot with plotCI from plotrix; see examples.

Value

None. However, a graphic is produced.
