Precision-recall curve for binary label prediction

Description

Precision-recall curve for binary label prediction

Usage

binaryPRC(
  scores,
  labels,
  cutoff = NULL,
  cut_direction = ">=",
  add_cut1 = FALSE,
  empty_precision = 1
)

Arguments

scores	Prediction score for each sample
labels	True labels for each sample, e.g., from simulation
cutoff	A vector of cutoffs; if NULL use all unique scores
cut_direction	A string to compare with cutoff: >=, >, <=, <
add_cut1	Logical value; if True, manually add a cutoff of 1
empty_precision	Float value for default precision if no any recall

Value

A data.frame containing recall and precision values at various cutoffs.

Examples

scores <- 1:10
labels <- c(0, 0, 0, 1, 0, 1, 0, 1, 1, 1)
binaryPRC(scores, labels)

# Extra arguments. 
binaryPRC(scores, labels, cutoff = seq(1, 10, by = 2))
binaryPRC(scores, labels, cut_direction = ">")
binaryPRC(scores, labels, add_cut1 = TRUE)
