thresholdLinkDf {MetCirc} | R Documentation

## 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 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.
