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 |
