Threshold a data frame containing information on links

Description

Threshold a link data frame based on lower and upper similarity values. The function will return the links 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 truncate 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.
