thresholdLinkDf: Threshold a data frame containing information on links

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

Description

Threshold a link data frame based on lower and upper similarity values. The function will return that lie within the defined bounds.

Usage

thresholdLinkDf(link0df, lower = 0.75, upper = 1)

Arguments

link0df	'data.frame', a link data frame that gives per each row information on linked features
lower	'numeric', threshold value for similarity values, below this value linked features will not be returned
upper	'numeric', threshold value for similarity values, above this value linked features will not be returned

Details

'lower' and 'upper' are numerical values and truncates mass spectra based on their similarity values.

Value

'thresholdLinkDf' returns a data frame that gives per each row information on linked features which are linked within certain thresholds.
