This function creates a pie plot of the values sampled of a set of selected
parameters. Numerical parameters are discretized to maximum
intervals. The size of the slices are proportional to the number of
configurations that have assigned a parameter value within the rank or the
value assigned to that slice. Parameters can be selected by providing their
names in the
sampling_pie(irace_results, param_names = NULL, n_bins = 3, filename = NULL)
The data generated when loading the
.Rdata file created by
irace (or the filename of that file).
String vector, A set of parameters to be included (example: param_names = c("algorithm","dlb"))
Numeric (default 3), number of intervals to generate for numerical parameters.
