sampling_heatmap2: Sampling heat map plot

Description

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

Usage

sampling_heatmap2(
  configurations,
  parameters,
  param_names,
  sizes = c(0, 0),
  filename = NULL
)

Value

sampling heat map plot

Arguments

configurations

Data frame, configurations in irace format (example: configurations = iraceResults$allConfigurations)

parameters

(list()) Parameter space in irace format. See the function irace::readParameters().

param_names

String vector of size 2, names of the parameters that should be included in the plot (example: param_names = c("beta","alpha"))

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))

filename

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

Examples

iraceResults <- read_logfile(system.file(package="irace", "exdata",
                                         "irace-acotsp.Rdata", mustWork = TRUE))
sampling_heatmap2(iraceResults$allConfigurations, iraceResults$scenario$parameters, 
                  param_names=c("beta", "alpha"))
