subset_metabolites_overlap {MiMIR}R Documentation

subset_metabolites_overlap

Description

Helper function that subsets the NH-metabolomics matrix features to the selection in metabolites needed for the metabolic score

Usage

subset_metabolites_overlap(x, metabos, quiet = FALSE)

Arguments

x

numeric data-frame with Nightingale-metabolomics

metabos

vector of strings containing the names of the metabolic features to be selected

quiet

logical to suppress the messages in the console

Value

matrix with the selected Nightingale-metabolomics features

References

This function is constructed to be able to apply the metaboAge as described in: van den Akker Erik B. et al. (2020) Metabolic Age Based on the BBMRI-NL 1H-NMR Metabolomics Repository as Biomarker of Age-related Disease. Circulation: Genomic and Precision Medicine, 13, 541-547, doi:10.1161/CIRCGEN.119.002610
