sampling_heatmap {iraceplot}

Sampling heat map plot

Description

Heatmap that displays the frequency of sampling values of two parameters.

Usage

sampling_heatmap(
  irace_results,
  param_names,
  sizes = c(0, 0),
  iterations = NULL,
  only_elite = TRUE,
  filename = NULL
)

Arguments

irace_results

The data generated when loading the .Rdata file created by irace (or the filename of that file).

param_names

(character()) Parameters to be included in the plot. Example: c("algorithm","alpha","rho","q0","rasrank").

sizes

Numeric vector that indicated the number of intervals to be considered for numerical parameters. This argument is positional with respect to param_names. By default, numerical parameters are displayed using 10 intervals. (example sizes = c(0,10))

iterations

Numeric vector, iteration number that should be included in the plot (example: iterations = c(1,4,5))

only_elite

logical (default TRUE), only print elite configurations.

filename

(character(1)) File name to save the plot, for example "~/path/example/filename.png".

Value

sampling heat map plot

Examples

iraceResults <- read_logfile(system.file(package="irace", "exdata",
                                         "irace-acotsp.Rdata", mustWork = TRUE))
sampling_heatmap(iraceResults, param_names=c("beta", "alpha"))
sampling_heatmap(iraceResults, param_names=c("beta", "alpha"), iterations = c(3,4))
sampling_heatmap(iraceResults, param_names=c("beta", "alpha"), only_elite = FALSE)
