Create plot from an ablation log

Create plot from an ablation log

ablation_plot(
  ablog,
  type = c("mean", "boxplot", "rank"),
  n = 0L,
  ylab = "Mean configuration cost",
  ylim = NULL,
  rotate_labs = TRUE,
  rename_labs = NULL,
  filename = NULL
)

Arguments

ablog

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

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 steps included in the plot. By default all steps from source to target are included.

ylab

Label of y-axis.

ylim

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

rotate_labs

logical(1)
Whether to rotate labels in x-axis. They are rotated by default because they are typically large.

rename_labs

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

filename

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

Value

ggplot2::ggplot() boxplot object

Examples

ablog <- read_ablogfile(system.file(package="irace", "exdata", "log-ablation.Rdata"))
ablation_plot(ablog)

ablation_plot(ablog, type="boxplot", rotate_labs = FALSE)

ablation_plot(ablog, type = "rank,boxplot", rename_labs =
              c("localsearch"="ls", algorithm="algo", source="default"))

ablation_plot(ablog, type="rank,mean,boxplot", n = 4, rotate_labs = FALSE)

ablog <- system.file(package="iraceplot", "exdata", "log-ablation-autoMOPSODTLZ.Rdata")
ablation_plot(ablog, type="rank,mean,boxplot")
