In sabarsi: Background Removal and Spectrum Identification for SERS Data

Description

Obtain the set of signature signals Merge groups of concatenated signals and give the time indices of signature signals.

Usage

merge_signals(xr, object, t.tol = 4, cor.tol = 0.5)

Arguments

xr	A p-length vector that represents a background-removed spectrum with p frequency channels.
object	An object obtained from signal_detection
t.tol	A positive integer, which is the tolerance of time difference when comparing two signals.
cor.tol	A number between 0 and 1. Two signals is considered to be similar enough if their correlation is higher than cor.tol.

Value

A vector recording the time indices of signature signals.

Examples

## xr is the matrix of background removed spectra.
res <- signal_detection(xr) ## detect the signals in xr
tim.index.ss <- merge_signals(xr = xr, object = res)  ## the set of signature signals.
