test_data

<p>Dataset mimicking structure of decoded UK Biobank dataset of NMR metabolomics
biomarker concentrations and associated processing variables for testing
package functions.</p>

datasets

A suite of utilities for working with the UK Biobank
<https://www.ukbiobank.ac.uk/> Nuclear Magnetic Resonance spectroscopy (NMR)
metabolomics data <https://biobank.ndph.ox.ac.uk/showcase/label.cgi?id=220>.
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>.
