plotPeak {MassSpecWavelet} | R Documentation |
Plot the identified peaks over the spectrum. The identified peaks are returned by peakDetectionCWT
or identifyMajorPeaks
plotPeak(ms, peakIndex = NULL, mz = 1:length(ms), range = c(min(mz), max(mz)), method = c("p", "l"), main = NULL, log = "", ...)
ms |

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. |
