findPeakWidth: findPeakWidth

Description Usage Arguments Value

View source: R/findPeakWidth.R

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

1
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.
