Plot parameter configurations using parallel coordinates — plot_configurations • iraceplot

Parallel coordinates plot of a set of provided configurations. Each line in the plot represents a configuration. The parameters to be included in the plot can be selected with the param_names argument. Additionally, the maximum number of parameters to be displayed in one plot. A list of plots is returned by this function in several plots are required to display the selected data.

plot_configurations(
  configurations,
  parameters,
  param_names = parameters$names,
  by_n_param = NULL,
  filename = NULL
)

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

(character()) Parameters to be included in the plot. Example: c("algorithm","alpha","rho","q0","rasrank").

by_n_param

Numeric (optional), maximum number of parameters to be displayed

filename

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