keggLibrary is an example of the keggCodes library used by the function addKeggCodes, which automates the substitution of compounds names by KEGG codes. keggLibrary is a data frame containing a list of KEGG compounds codes in the first column and their respective names in the second column.
metabolomicsData is an example of a typical metabolomics data set, where it has a list of identified metabolites in the first column and their respective abundances in the different samples in the following columns. The first row of metabolomicsData, Replicates, defines to which experimental condition each sample belongs.
papiData is a data frame containing a list of identified metabolites in the first column, in this case represented by their respective KEGG codes, and their abundances in the different samples in the following columns.
An example of the data frame produced by papi, where the first column contains the name of the metabolic pathways identified and the following columns contains their respective Activity Score (AS) in the different samples analyzed.
