Peak detection parameter setup

Description

Peak detection parameter setup

Usage

PeakdetectionParam(
  peakwidth = c(5, 30),
  snthr = 3,
  prefilter = c(3, 100),
  fitgauss = FALSE,
  method.peakdetection = c("centWave", "localMax"),
  method.roi = c("continuous", "aroundMax"),
  method.baseline = c("xcms", "centWaveP"),
  method.smooth = c("Gaussian", "LOESS", "SG")
)

Arguments

`peakwidth`	'numeric(2)' with the lower and upper bound of the expected peak width.
`snthr`	'numeric(1)' defining the signal to noise ratio cutoff. Peaks with a signal to noise ratio < 'snthr' are omitted.
`prefilter`	'numeric(2)' ('c(k, I)'): only regions of interest with at least 'k' centroids with signal '>= I' are returned in the first step.#'
`fitgauss`	'logical(1)' whether or not a Gaussian should be fitted to each peak.
`method.peakdetection`	'character(1)' method for peak detection
`method.roi`	method for finding rois in extracted EICs. [] 'continuous' - traditional centwave roi finding method [] 'aroundMax' - finding local maximums and determing a scan range based on the peakwidth to define the roi range
`method.baseline`	method for determing baselines, only xcms supported currently
`method.smooth`	'character(1)' method for smoothing the EICs (Gaussian, LOESS and SG)
