plotNDSet2D: Create a plot of a discrete non-dominated set.

In gMOIP: Tools for 2D and 3D Plots of Single and Multi-Objective Linear/Integer Programming Models

Create a plot of a discrete non-dominated set.

Description

Create a plot of a discrete non-dominated set.

Usage

plotNDSet2D(
  points,
  crit,
  addTriangles = FALSE,
  addHull = TRUE,
  latex = FALSE,
  labels = NULL
)

Arguments

points	Data frame with non-dominated points.
crit	Either max or min (only used if add the iso-profit line). A vector is currently not supported.
addTriangles	Add search triangles defined by the non-dominated extreme points.
addHull	Add the convex hull and the rays.
latex	If true make latex math labels for TikZ.
labels	If NULL don't add any labels. If 'n' no labels but show the points. If equal coord add coordinates to the points. Otherwise number all points from one.

Value

The ggplot object.

Note

Currently only points are checked for dominance. That is, for MILP models some nondominated points may in fact be dominated by a segment.

Examples

dat <- data.frame(z1=c(12,14,16,18,18,18,14,15,15), z2=c(18,16,12,4,2,6,14,14,16))
points <- addNDSet(dat, crit = "min", keepDom = TRUE)
plotNDSet2D(points, crit = "min", addTriangles = TRUE)
plotNDSet2D(points, crit = "min", addTriangles = FALSE)
plotNDSet2D(points, crit = "min", addTriangles = TRUE, addHull = FALSE)
points <- addNDSet(dat, crit = "max", keepDom = TRUE)
plotNDSet2D(points, crit = "max", addTriangles = TRUE)
plotNDSet2D(points, crit = "max", addHull = FALSE)
