assign_hierarchy Assign hierarchy metadata
c57_nos2KO_mouse_countDF c57b6J nos2KO metabolomics count matrix
c57_nos2KO_mouse_metadata c57b6J nos2KO meta data
check_zeros Check data for zeros across samples within factor levels. Will determine if there are more zeros than a user specified threshold within any given factor level(s). Returns a vector of Metabolites that are 0 above the threshold in any given factor level.
