The 'sampling_frequency' function creates a frequency or density plot that depicts the sampling performed by irace across the iterations of the configuration process.
For categorical parameters a frequency plot is created, while for numerical parameters a histogram and density plots are created. The plots are shown in groups of maximum 9, the parameters included in the plot can be specified by setting the param_names argument.

irace_results,
param_names = NULL,
n = NULL,
file_name = NULL
)

irace_results |
The data generated when loading the |
param_names |
String vector, A set of parameters to be included (example: param_names = c("algorithm","alpha","rho","q0","rasrank")) |
n |
Numeric, for scenarios with large parameter sets, it selects a subset of 9 parameters. For example, n=1 selects the first 9 (1 to 9) parameters, n=2 selects the next 9 (10 to 18) parameters and so on. |
file_name |
String, file name to save plot. If there are more than 9 parameters, a pdf file extension is recommended as it allows to create a multi-page document. Otherwise, you can use the n argument of the function to generate the plot of a subset of the parameters. (example: "~/path/to/file_name.pdf") |
