parallelCoordinatesPlot

parallelCoordinatesPlot

Description

parallelCoordinatesPlot plots a set of parameter configurations in parallel coordinates.

Usage

parallelCoordinatesPlot(configurations, parameters,
  param_names = parameters$names, hierarchy = TRUE, filename = NULL,
  pdf.width = 14, mar = c(8, 1, 4, 1))

Arguments

configurations

(data.frame)
Parameter configurations of the target algorithm (one per row).
parameters

(list())
Data structure containing the parameter space definition. The data structure has to similar to the one returned by the function readParameters.
param_names

Parameters names that should be included. Default: parameters$names.
hierarchy

If TRUE conditional parameters will be displayed in a different plot. Default TRUE.
filename

Filename prefix to generate the plots. If NULL the plot displayed but not saved.
pdf.width

Width for the pdf file generated.
mar

Margin to use for the plot. See par.

Value

A set of parallel coordinates plots showing the parameters values. If a filename is provided this plots are saved in one or more files.

Examples

## To use data obtained by irace
 # First, load the data produced by irace.
 irace.logfile <- file.path(system.file(package="irace"), "exdata", "irace-acotsp.Rdata")
 load(irace.logfile)
 attach(iraceResults)
