createLinkDf {MetCirc} | R Documentation

## Create a data frame which contains features to link (indices)

### Description

Create a data frame which contains features to link (indices).

### Usage

    createLinkDf(similarityMatrix, spectra, condition, lower, upper)

### Arguments

`similarityMatrix` | 'matrix', a similarity matrix that contains the similarity measure between all precursors in the data set
`spectra` | MSpectra object containing spectra of similarityMatrix
`condition` | 'character', vector containing the conditions/samples for which a linkDf is created
`lower` | 'numeric', threshold value for similarity values, below this value linked features will not be included
`upper` | 'numeric', threshold value for similarity values, above this value linked features will not be included

### Details

'lower' and 'upper' are numerical values and truncate similar spectra. The function createLinkDf is a wrapper for the functions 'createLink0df' and 'thresholdLinkDf'.

### Value

'createLinkDf' returns a data frame that gives per each row information on linked features

### Examples

    data("spectra", package = "MetCirc")
    data("similarityMat", package = "MetCirc")
    link0df <- createLink0df(similarityMatrix = similarityMat,
        spectra_tissue, condition = c("SPL", "LIM", "ANT", "STY"))
    createLinkDf(similarityMatrix = similarityMat, spectra = spectra_tissue,
        condition = c("SPL", "LIM", "ANT", "STY"), lower = 0.5, upper = 1)
