Creating a Screeplot for an epplab Object

Description

Plots the objective criteria of an epplab object versus the simulation runs.

Usage

## S3 method for class 'epplab'
screeplot(x, type = "lines", which = 1:10, main = "",
  ylab = "Objective criterion", xlab = "Simulation run", ...)

Arguments

Details

The option which can restrict the output to certain simulation runs. In case of many simulations, this might improve the readability. The barplot option is often not meaningful, because the objective criteria are usually large and bars begin by default at zero.

Examples

library(tourr)
data(olive)
res <- EPPlab(olive[,3:10],PPalg="PSO",PPindex="KurtosisMin",n.simu=10, maxiter=20)
screeplot(res)

# Pretty useless:
screeplot(res,type="barplot")

screeplot(res,which=1:5)
