Parallel Coordinates Plot — parallel

The `parallel_coord` function creates a parallel coordinates plot of a set of selected configurations. Each line in the plot represents a configuration. By default, the final elite configurations are shown. To visualize configurations of other iterations these must be provided setting the argument iterations, configurations of different iterations are shown in different colors. Setting the only_elites argument to FALSE allows to display all configurations in the selected iterations, specific configurations can be selected providing their ids in the id_configuration argument.

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.

To export the plot to a file, it is possible to do it so manually using the functionality provided by plotly in the plot. If a file_name is provided, orca server will be used to export the plots and thus, it requires the library to be installed (https://github.com/plotly/orca).

parallel_coord(
  irace_results,
  id_configuration = NULL,
  param_names = NULL,
  iterations = NULL,
  only_elite = TRUE,
  by_n_param = NULL,
  file_name = NULL
)

Arguments

irace_results	The data generated when loading the `Rdata` file created by `irace`
id_configuration	Numeric vector, configurations ids whose performance should be included in the plot (example: id_configuration = c(20,50,100,300,500,600,700))
param_names	String vector, names of the parameters that should be included in the plot (example: param_names = c("algorithm","alpha","rho","q0","rasrank"))
iterations	Numeric vector, iteration number that should be included in the plot (example: iterations = c(1,4,5))
only_elite	logical (default TRUE), only print elite configurations (argument ignored when id_configuration is provided)
by_n_param	Numeric (optional), maximum number of parameters to be displayed.
file_name	String, file name to save plot (example: "~/patch/example/file_name.png"). Orca is required. See more details in: https://github.com/plotly/orca.
