multibc: Multiple Metabolomics Fingerprint Baseline Correction

Description Usage Arguments Value Author(s) See Also Examples

Description

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

Usage

1
  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.
