getAccuracyMN {biosigner} | R Documentation

## 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

    getAccuracyMN(object, ...)

    ## S4 method for signature 'biosign'
    getAccuracyMN(object)

### Arguments

`object` | An S4 object of class `biosign`, created by the `biosign` function.
`...` | Currently not used.

### 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)

### Author(s)

Philippe Rinaudo and Etienne Thevenot (CEA)

### 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)
