plotNDSet2D {gMOIP}

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)
