DetectPeaks_C: DetectPeaks_C.

In prafols/rMSIproc: MSI Processing in C++

Description

Detect peaks from a Rcpp::NumericVector object and returns data in a R matrix. This method is only exported to be use by R function DetectPeaks which is an actual R function. The returned peak positions follows C indexing style, this is starts with zero.

Usage

DetectPeaks_C(mass, intensity, SNR = 5, WinSize = 20L, UpSampling = 10L)

Arguments

mass	a NumericVector containing the mass axis of the spectrum.
intensity	a NumericVector where peaks must be detected.
SNR	Only peaks with an equal or higher SNR are retained.
WinSize	The windows used to detect peaks and caculate noise.
UpSampling	the oversampling used for acurate mass detection and area integration.

Value

a NumerixMatrix of 5 rows corresponding to: mass, intensity of the peak, SNR, area and binSize.
