ukbnmr: Removal of Unwanted Technical Variation from UK Biobank NMR Metabolomics Biomarker Data

A suite of utilities for working with the UK Biobank <> Nuclear Magnetic Resonance spectroscopy (NMR) metabolomics data <>. Includes functions for extracting biomarkers from decoded UK Biobank field data, removing unwanted technical variation from biomarker concentrations, computing an extended set of lipid, fatty acid, and cholesterol fractions, and for re-deriving composite biomarkers and ratios after adjusting data for unwanted biological variation. For further details on methods see Ritchie SC et al. Sci Data (2023) <doi:10.1038/s41597-023-01949-y>.
