Box Plot Testing

The `boxplot_test` function creates a box plot that displays the performance of a set of configurations on the test instances.

The performance data is obtained from the test evaluations performed by irace. Note that the testing is not a default feature in irace and should be enabled in the setup (see the irace package user guide for more details).

boxplot_test(irace_results, type = "all", rpd = TRUE, file_name = NULL)

Arguments

irace_results	The data generated when loading the Rdata file created by irace
type	String, (default "all") possible values are "all", "ibest" or "best". "all" shows all the configurations included in the test, "best" shows the elite configurations of the last iteration and "ibest" shows the elite configurations of each iteration. Note that "ibest" requites that irace includes the iteration elites in the testing.
rpd	Logical, (default TRUE) TRUE to plot performance as the relative percentage deviation to best results per instance, FALSE to plot raw performance.
file_name	String, File name to save plot (example: "~/patch/example/file_name.png")

Value

box plot

Examples

boxplot_test(iraceResults)
boxplot_test(iraceResults, rpd = FALSE)
boxplot_test(iraceResults, type = "ibest")
boxplot_test(iraceResults, type = "best")
