plotPeak {MassSpecWavelet} | R Documentation

## Plot the identified peaks over the spectrum

### Description

Plot the identified peaks over the spectrum. The identified peaks are returned by `peakDetectionCWT` or `identifyMajorPeaks`

### Usage

    plotPeak(ms, peakIndex = NULL, mz = 1:length(ms), range = c(min(mz), max(mz)), method = c("p", "l"), main = NULL, log = "", ...)

### Arguments

`ms` | the MS spectrum
`peakIndex` | m/z indexes of the identified peaks
`mz` | m/z value correspond to m/z index
`range` | the plot range of m/z value
`method` | plot method of the identified peaks. method 'p' plot circles on the peaks; method 'l' add vertical lines over the peaks.
`main` | parameter of `plot`
`log` | parameter of `plot`
`...` | other parameters of `points`

### Examples

            data(exampleMS)
            SNR.Th <- 3
            peakInfo <- peakDetectionCWT(exampleMS, SNR.Th=SNR.Th)
            majorPeakInfo = peakInfo$majorPeakInfo
            peakIndex <- majorPeakInfo$peakIndex
            plotPeak(exampleMS, peakIndex, main=paste('Identified peaks with SNR >', SNR.Th))
