getCoefficients {metabCombiner} | R Documentation

## Obtain Last-Used Score Coefficients

### Description

Provides the last used weight arguments from `calcScores()` function. Returns empty list if `calcScores()` has not yet been called.

### Usage

    getCoefficients(object)

    ## S4 method for signature 'metabCombiner'
    getCoefficients(object)

### Arguments

`object` | metabCombiner object

### Value

A list of the last used weight parameters:

`A` | Specific weight penalizing feature m/z differences
`B` | Specific weight penalizing retention time projection error
`C` | Specific weight penalizing differences in abundance quantiles

### Examples

    data(plasma30)
    data(plasma20)

    p30 <- metabData(plasma30, samples = "CHEAR")
    p20 <- metabData(plasma20, samples = "Red")

    p.comb <- metabCombiner(p30, p20)
    p.comb <- selectAnchors(p.comb, windx = 0.05, windy = 0.04, tolrtq = 0.15)
    p.comb <- fit_gam(p.comb, k = 20, iterFilter = 1, family = "gaussian")
    p.comb <- calcScores(p.comb, A = 90, B = 14, C = 0.5)

    getCoefficients(p.comb)
