This repository contain R scripts for metabolomic data analysis. The scripts were developed based on the research at LabMetaMass.
LabMetaMass is a research group at the University of Campinas, São Paulo, headed by Prof. Dr. Alexandra C. H. F. Sawaya. The group focuses on the Metabolomic data analysis of Brazilian medicinal plants and how environmental and agricultural conditions affect the metabolism of such herbal medicines.
Metabolomics research usually starts with sample analysis using an LC-MS equipment. The data generated by this technique, then, is pre-processed before initial statistical analysis. After the pre-processing, exploratory data analysis is performed, following by typical and appropriate statistical tests.
Notice that they contain detailed comments, as their use was also intended for members with no experience in R language.
