TestDataC: R6 class of test dataset for Precision-Recall curve evaluation

Description

TestDataC is a class that contains scores and label for performance evaluation tools. It provides necessary methods for curve evaluation.

Usage

TestDataC

format

An R6 class object.

Methods

• set_basepoints_x(x): Set pre-calculated recall values for curve evaluation
• set_basepoints_y(y): Set pre-calculated precision values for curve evaluation
• get_basepoints_x(): Get pre-calculated recall values for curve evaluation
• get_basepoints_y(): Get pre-calculated precision values for curve evaluation
• set_textpos_x(x): Set the x position for displaying the test result in a plot
• set_textpos_y(y): Set the y position for displaying the test result in a plot
• get_textpos_x(): Get the x position for displaying the test result in a plot
• get_textpos_y(): Get the y position for displaying the test result in a plot

Following seven methods are inherited from TestDataB. See TestDataB for the method descriptions.

• get_datname()
• get_scores()
• get_labels()
• get_fg()
• get_bg()
• get_fname()
• del_file()

create_testset for creating a list of test datasets. It is derived from TestDataB.

Examples

## Initialize with scores, labels, and a dataset name
testset <- TestDataC$new(c(0.1, 0.2), c(1, 0), "c4")

## Set base points
testset$set_basepoints_x(c(0.13, 0.2))
testset$set_basepoints_y(c(0.5, 0.6))
