Abstract

This chapter explains the basic R functions needed for data import and export operations, and for handling vectors, data tables and qualitative variables (factors). This introductory presentation is limited to a few key elements needed for multivariate data analysis in Ecology with the ade4 package. It is not intended as a general introduction to R, and if needed, the reader should refer to a basic book on R. See, for example, here: https://cran.r-project.org/manuals.html or here: https://cran.r-project.org/other-docs.html.
