multibc: Multiple Metabolomics Fingerprint Baseline Correction

In wilsontom/FIEmspro: Flow In-jection Electrospray Mass Spectrometry Processing: \\ data processing, classification modelling and variable selection in metabolite fingerprinting

Description

Wrapper for function onebc for several samples. An additional plotting parameter for visualizing the baseline correction process is added.

Usage

  multibc(x,wsize=50,qtl=0.1,maxy=1000,plotting=FALSE,pause=0)

Arguments

x	A data frame or matrix to be processed.
wsize	Window size.
qtl	A numeric value of probability with values in [0,1].
maxy	A numeric value which specifies maximal intensity to be plotted on y axis.
plotting	A logical value indicating whether or not plotting.
pause	Time interval defining pause between each baseline correction in order to visualise each individual plot during the BC process if plotting is TRUE.

Value

A list containing the following components:

x	Sample matrix after baseline subtraction.
bsl	Baseline matrix.
