baseline.corr: Baseline Correction using asymmetric least squares

Description

This function estimates a baseline using asymmetric least squares and subtracts it from the data.

Usage

baseline.corr(y, ...)

Arguments

y

signal(s) to correct. This can be a vector (containing one signal) or a matrix of signals(one signal per row)

…

other arguments to the asysm function.

Value

ycorr

baseline corrected signal(s): a vector or a matrix of the same dimension as the input signal(s)
