createLink0df: Create a link matrix

In tnaake/MetCirc: Navigating mass spectral similarity in high-resolution MS/MS metabolomics data metabolomics data

Create a link matrix

Description

Create a link matrix which links every feature in similarity matrix with another.

Usage

createLink0df(similarityMatrix, sps, condition)

Arguments

similarityMatrix	matrix, a similarity matrix that contains the NDP similarity measure between all precursors in the data set
sps	Spectra object
condition	character, which conditions should be included?

Details

createLink0df creates a matrix from a similarity matrix which includes all connections between features in the similarity matrix, but exclude links which have a similarity of exactly 0.

Value

createLink0df returns a 'matrix' that gives per each row information on linked features
