Abstract

In this chapter, plain R recipes are presented to produce the most common graphs used in igneous geochemistry, such as binary plots (simple and multiple, e.g. Harker plots), ternary plots or spiderplots. Practical exercises illustrating the general principles are also included. Special attention is given to dealing with spurious correlations in binary plots (closure effect). The fundamentals and implementation of classification and geotectonic diagrams in GCDkit are also mentioned, as are the relevant commands for drawing basic plot types (binary, ternary, spider and multiple) and their subsequent modification.
