print.PRROC {PRROC}

printing PRROC objects

Description

Prints a PRROC object.

Usage

## S3 method for class 'PRROC'
print(x, ...)

Arguments

x

a PRROC object obtained from pr.curve or roc.curve

...

see print

Details

The print method for PRROC objects prints the area under the (PR or ROC) curve, and (if curve=TRUE in pr.curve or roc.curve) the range of classification scores. If also max.compute=TRUE, min.compute=TRUE, and/or rand.compute=TRUE when the PRROC object has been computes using pr.curve or roc.curve, a relative area under curve is reported, i.e., the minimal AUC subtracted from the original AUC and the result divided by the difference of maximum and minimum AUC.

Examples

# create artificial scores as random numbers
x <- rnorm( 1000 );
y <- rnorm( 1000, -1 );
# compute area under PR curve
pr <- pr.curve( x, y );
print( pr );

# compute area under ROC curve
roc <- roc.curve( x, y );
print( roc );
