biosigner (version 1.0.4)

getAccuracyMN: Accuracies of the full model and the models restricted to the signatures

Description

Balanced accuracies for the full models, and the models restricted to the 'S' and 'AS' signatures

Usage

## S3 method for class 'biosign':
getAccuracyMN(object)

Arguments

object

An S4 object of class biosign, created by the biosign function.

Value

• A numeric matrix containing the balanced accuracies for the full models, and the models restricted to the 'S' and 'AS' signatures (predictions are obtained by using the resampling scheme selected with the 'bootI' and 'crossvalI' arguments)

Examples

## loading the diaplasma dataset

data(diaplasma)
attach(diaplasma)

## restricting to a smaller dataset for this example

featureSelVl <- variableMetadata[, "mzmed"] >= 490 & variableMetadata[, "mzmed"] < 500
dataMatrix <- dataMatrix[, featureSelVl]
variableMetadata <- variableMetadata[featureSelVl, ]

## signature selection for all 3 classifiers
## a bootI = 5 number of bootstraps is used for this example
## we recommend to keep the default bootI = 50 value for your analyzes

set.seed(123)
diaSign <- biosign(dataMatrix, sampleMetadata[, "type"], bootI = 5)

## individual boxplot of the selected signatures

getAccuracyMN(diaSign)

detach(diaplasma)
