combinedTable {metabCombiner} | R Documentation

## Obtain Feature Alignment Report

### Description

Obtain constructed table reporting every possible metabolomics feature pair alignment.

### Usage

    combinedTable(object)

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

### Arguments

`object` | `metabCombiner` object.

### Value

Feature Pair Alignment report data frame. The columns of the report are as follows:

`idx` | Identities of features from dataset X
`idy` | Identities of features from dataset Y
`mzx` | m/z values of features from dataset X
`mzy` | m/z values of features from dataset Y
`rtx` | retention time values of features from dataset X
`rty` | retention time values of features from dataset Y
`rtProj` | model-projected (X->Y) retention times values
`Qx` | abundance quantile values of features from dataset X
`Qy` | abundance quantile values of features from dataset Y
`group` | m/z feature group of feature pairing
`score` | computed similarity scores of feature pairing
`rankX` | ranking of pairing score for X dataset features
`rankY` | ranking of pairing score for Y dataset features
`adductX` | adduct label of features from dataset X
`adductY` | adduct label of features from dataset Y
`...` | Sample and extra columns from both datasets X & Y

### Examples

    data(plasma30)
    data(plasma20)

    p30 <- metabData(head(plasma30,500), samples = "CHEAR")
    p20 <- metabData(head(plasma20,500), samples = "Red")

    p.comb <- metabCombiner(p30, p20)
    p.comb.table <- combinedTable(p.comb)
