plotAblation function

Create plot from an ablation log

plotAblation(
  ablog,
  pdf_file = NULL,
  width = 20,
  height = 7,
  type = c("mean", "boxplot", "rank"),
  n = 0L,
  mar = NULL,
  ylab = "Mean configuration cost",
  ylim = NULL,
  rename_labels = NULL,
  ...
)

Arguments

• ablog: (list()|character(1)) Ablation log object returned by ablation(). Alternatively, the path to an .Rdata file, e.g., "log-ablation.Rdata", from which the object will be loaded.

• pdf_file: Output filename.

• width: Width provided to create the PDF file.

• height: Height provided to create the PDF file.

• type: Type of plot. Supported values are "mean" and "boxplot". Adding "rank" will plot rank per instance instead of raw cost value.

• n: integer(1)

  Number of parameters included in the plot. By default all parameters are included.

• mar: Vector with the margins for the ablation plot.

• ylab: Label of y-axis.

• ylim: Numeric vector of length 2 giving the y-axis range.

• rename_labels: character()

  Renaming table for nicer labels. For example, c("No value"="NA", "LongParameterName"="LPN").

• ...: Further graphical parameters may also be supplied as arguments. See graphics::plot.default().

Examples

logfile <- file.path(system.file(package="irace"), "exdata", "log-ablation.Rdata")
plotAblation(ablog = logfile)
plotAblation(ablog = logfile, type = "mean")
plotAblation(ablog = logfile, type = c("rank","boxplot"), rename_labels = c(
            "localsearch"="ls", algorithm="algo", source="default"))
