plotF1Measure: Plot the F1 measure efficiency frontier using the sparse thresholdSummary data frame

Description

Plot the F1 measure efficiency frontier using the sparse thresholdSummary data frame

Usage

plotF1Measure(
  plpResult,
  typeColumn = "evaluation",
  saveLocation = NULL,
  fileName = "roc.png"
)

Value

A ggplot object. Use the ggsave function to save to file in a different format.

Arguments

plpResult

A plp result object as generated using the runPlp function.

typeColumn

The name of the column specifying the evaluation type

saveLocation

Directory to save plot (if NULL plot is not saved)

fileName

Name of the file to save to plot, for example 'plot.png'. See the function ggsave in the ggplot2 package for supported file formats.

Details

Create a plot showing the F1 measure efficiency frontier using the sparse thresholdSummary data frame

Examples

  # takes too long 
data("simulationProfile")
plpData <- simulatePlpData(simulationProfile, n=1000)
saveLoc <- file.path(tempdir(), "plotF1Measure")
results <- runPlp(plpData, outcomeId = 3, saveDirectory = saveLoc)
plotF1Measure(results)
# clean up
unlink(saveLoc, recursive = TRUE)
