Met.Binning {Metabonomic}R Documentation

Binning

Description

The function 'binning' takes a matrix of spectra and constructs a matrix of intensities of reduced dimensions based on an equally spaced mesh of interval breaks.

Usage

Met.Binning(datos)

Arguments

datos Spectra data frame

Details

The most common method of reducing the influence of shifting peaks is the so-called binning or bucketing method, which reduces the spectrum resolution. Thereby the spectra are integrated within small spectral regions, called ''bins'' or ''buckets''. Subsequent data analysis procedures, which are applied to the binned spectra, are not influenced by peak shifts, as long as these shifts remain within the borders of the corresponding bins. After launching the Binning graphical applications (Preprocessing / Binning), the user can select the bin size. The spectra integration is performed by running the ''binning'' function from the PROcess library. Launched with the GUI. Beta version.
