Sampling heat map plot — sampling

Heatmap that displays the frequency of sampling values of two parameters.

sampling_heatmap2(
  configurations,
  parameters,
  param_names,
  sizes = c(0, 0),
  filename = NULL
)

Arguments

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: String vector of size 2, names of the parameters that should be included in the plot (example: param_names = c("beta","alpha"))
sizes: Numeric vector that indicated the number of intervals to be considered for numerical parameters. This argument is positional with respect to param_names. By default, numerical parameters are displayed using 10 intervals. (example sizes = c(0,10))
filename: (character(1)) File name to save the plot, for example "~/path/example/filename.png".

                  param_names=c("beta", "alpha"))
