MetNorm-package: MetNorm

Description

Statistical methods for normalizing metabolomics data

Details

Metabolomics data are inevitably subject to a component of unwanted variation, due to factors such as batch effects, matrix effects, and confounding biological variation. This package contains a collection of R fuctions which may be used to obtain normalized metabolomics data.
