mzGroup: Binning of mass spectral features in m/z dimension

In hhabra/metabCombiner: Method for Combining LC-MS Metabolomics Feature Measurements

Binning of mass spectral features in m/z dimension

Description

Features in two input feature lists are grouped by their m/z values.

Usage

mzGroup(xset, yset, binGap)

Arguments

xset	data frame containing metabolomics features
yset	data frame containing metabolomics features
binGap	numeric gap value between consecutive sorted & pooled feature m/z values.

Details

The m/z values from both datasets are pooled, sorted, and binned by the binGap argument. Feature groups form when there is at least one pair of features from both datasets whose consecutive difference is less than binGap. Grouped features are joined together in combinedTable data report.

Value

list object containing updated xset & yset with group information
