annotations2tab {metaMS} | R Documentation

## Conversion of a list of annotation results into a table

### Description

Function `annotations2tab` converts the output of `matchSamples2DB` into a table, in the case of multiple DB hits for one pseudospectrum distinguishing the “best” hit from the “alternative” hits. Function `makeAnnotation` prepares a `data.frame` object with the correct number of rows. Both functions are not meant to be called directly by the user.

### Usage

    annotations2tab(annlist, matches)
    makeAnnotation(n)

### Arguments

`annlist` | Annotation list, output of `matchSamples2DB`.
`matches` | Object containing all match factors - needed to distinguish the best match from the rest in the case of a double annotation.
`n` | Number of rows in the annotation `data.frame` (possibly zero).

### Value

A three-column `data.frame`, containing the numbers of the pseudospectrum in the experimental data, the numbers of the best hits in the DB, and finally the alternative hits ain the DB
