findPeakWidth {Autotuner} | R Documentation

## findPeakWidth

### Description

This function is designed to find the maximum peakwidth of an EIC observed within a given TIC peak. It does so by using checkBounds to estimate width in time of a peak and countMaxima to determine if a peak may be made up from two similar structural isomers.

### Usage

    findPeakWidth(approvScorePeaks, mzDb, header, sortedAllEIC, boundaries, ppmEst)

### Arguments

`approvScorePeaks` | A data.frame containing information on the retained bins.
`mzDb` | A list of data.frames containing the m/z and intensity values from each scan's mass spectra.
`header` | A data.fame containing metadata on the sample like spectra type (MS1 vs MS2), retention time, and scan count.
`sortedAllEIC` | A data.frame containing observed EIC values along with their corresponsing scan ID.
`boundaries` | A numeric vector with indicies representing the scans bounding the original TIC peak.
`ppmEst` | A scalar value representing the calculated ppm error used to generate data.

### Value

This function returns a scalar value representing an estimate for the maximal peak width across samples.
