irace (version 3.4.1)

parameterFrequency: Plot of histogram of parameter values

Description

parameterFrequency plots the frequency of the parameters values in a set of target algorithm configurations. It generates plots showing the frequency of parameter values for each parameter, with rows * cols parameters being shown per plot. If a filename is provided the plots are saved in one or more files.

Usage

parameterFrequency(configurations, parameters, rows = 4, cols = 3,
  filename = NULL, pdf.width = 12, col = "gray")

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.

rows

Number of plots per column.

cols

Number of plots per row.

filename

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

pdf.width

Width for the pdf file generated.

col

Color of the bar plot.
