Methods

Public methods

• Precision$new()

• Precision$compute()

• Precision$clone()

Method new()

Method for initializing the object arguments during runtime.

Usage

Precision$new(performance.output = NULL)

Arguments

performance.output

An optional ConfMatrix parameter to define the type of object used as basis to compute the measure.

Method compute()

The function computes the Precision achieved by the M.L. model.

Usage

Precision$compute(performance.output = NULL)

Arguments

performance.output

An optional ConfMatrix parameter to define the type of object used as basis to compute the Precision measure.

Details

This function is automatically invoke by the ClassificationOutput object.

Returns

A numeric vector of size 1 or NULL if an error occurred.

Method clone()

The objects of this class are cloneable with this method.

Usage

Precision$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
