count_fold_changes      Get counts for significant fold changes by
                        metabolite class.
make_omelette           Get metadata from KEGG API
omu_anova               Perform anova Performs an anova across all
                        response variables. The function can take a
                        maximum of 2 independent variables and perform
                        an interaction term between them.
omu_summary             omu_summary Performs t test, standard
                        deviation, standard error, FDR correction, fold
                        change, log2FoldChange. The order effects the
                        fold change values
pie_chart               Create a pie chart
plate_omelette          plate_omelette Internal method for KEGG_Gather
plate_omelette_rxnko    Clean up orthology metadata
plot_bar                Create a bar plot
plot_volcano            Create a volcano plot
ra_table                Creates a ratio table from the
                        count_fold_changes function output.
