metric: Calculate metric

In computational-metabolomics/struct: Statistics in R Using Class-based Templates

Calculate metric

Description

A class for metrics to assess performance of e.g. models, iterators. Not intended to be called directly, this class should be inherited to provide functionality for method-specific classes.

Usage

calculate(obj, ...)

value(obj)

value(obj) <- value

max_length(obj) <- value

metric(...)

## S4 method for signature 'metric'
calculate(obj, Y, Yhat)

## S4 method for signature 'metric'
value(obj)

## S4 replacement method for signature 'metric'
value(obj) <- value

Arguments

obj	a metric object
...	named slots and their values.
value	value
Y	the true class labels
Yhat	the predicted class labels

Value

value the calculated value of a metric

a metric object

Examples

MET = metric()
calculate(MET)
MET = metric()
M = metric()
calculate(M,Y,Yhat)
MET = metric()
value(MET)
MET = metric()
value(MET) = 10
