centWaveP: CWT Based Chromatographic Peak Detection

Description Usage Arguments Value Attribution See Also

cent.xr A wrapper for xcmsRaw objects. See cent

1	cent.xr(xr, ppm = 2, prefilter = c(0, 0), maxskip = 0)

`ppm`	numeric the ppm mass error acceptable before a new ROI is initialized. This ppm is allowed on both sides of the mass.
`prefilter`	numeric a two integer vector. The first indicates the minimum number of peaks an ROI must contain to be retained. The second indicates the minimum intensity those muct be.
`maxskip`	integer The number of scans an ROI must not contain a peak before clossing the ROI. This is an addition to the original algorithm. Useful for QE data.

A list, one entry for each region of interest.

This code was modified from the originally published centWave algorithm [1]. The code was orginally distributed and obtained under the GPL2 license via the xcms software package [2]. The original algorithms depend on the wavelet analysis code included in the MassSpecWavelet package [3]. All code herein was obtained under the GPL2 license and remains under the GPL 3 license or greater.
