add.frame {BMAmevt}

Adds graphical elements to a plot of the two dimensional simplex.

Description

Adds graphical elements to the current plot (on the two-dimensional simplex).

Usage

add.frame(
  equi = FALSE,
  lab1 = "w1",
  lab2 = "w2",
  lab3 = "w3",
  npoints = 60,
  col.polygon = "black",
  axes = TRUE
)

Arguments

equi

logical. Is the simplex represented as an equilateral triangle (if TRUE) or a right triangle (if FALSE) ?

lab1

Character string: label for first component.

lab2

Character string: label for second component.

lab3

Character string: label for third component.

npoints

The number of grid nodes on the squared grid containing the desired triangle.

col.polygon

The background color outside the simplex.

axes

logical. Should axes be added ?

Details

Generic graphical tool for obtaining nice plots of the two-dimensional simplex

Examples

plot.new()
add.frame()
plot.new()
mult.x=sqrt(2); mult.y=sqrt(3/2)
plot.window( xlim=c(0,mult.x),ylim=c(0,mult.y), asp=1,bty ="n")
add.frame(equi=TRUE)
