Heatmap that displays the frequency of sampling values of two parameters.
sampling_heatmap( irace_results, param_names, sizes = c(0, 0), iterations = NULL, only_elite = TRUE, filename = NULL )
The data generated when loading the
.Rdata file created by
irace (or the filename of that file).
character()) Parameters to be included in the plot. Example:
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))
Numeric vector, iteration number that should be included in the plot (example: iterations = c(1,4,5))
logical (default TRUE), only print elite configurations.
character(1)) File name to save the plot, for example
