In zeehio/MassSpecWavelet: Peak Detection for Mass Spectrometry data using wavelet-based algorithms

Find local maxima and return the size of the window where they are maximum.

Description

Compared to the rest of the package, this is a rather experimental function. If you plan to use it or are interested in it, please open an issue at https://github.com/zeehio/MassSpecWavelet/issues to show your interest.

Usage

findLocalMaxWinSize(x, capWinSize = NA)

Arguments

x	A numeric vector.
capWinSize	the maximum window size to report. NA means unlimited.

Value

An integer vector y of the same length as x. y[i] will be the size of the largest window on x containing x[i] where:

• x[i] is a local maximum or a center of a plateau

• x[i] is not at a window border Optionally, if capWinSize is a positive integer, the maximum window size is capped to that value, to increase performance. Use this in case you just want to check if there exists a window of that size. @export @examples x <- c(1, 2, 3, 2, 1) findLocalMaxWinSize(x)
