MiMIR (version 1.5)

subset_metabolites_overlap: 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)

Value

matrix with the selected Nightingale-metabolomics features

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

References

This function is constructed to be able to apply the metaboAge as described in: van den Akker Erik B. et al.
