rim - R’s Interface to Maxima

Maxima is a OpenSource, fairly complete and powerful computer algebra system (CAS). rim can be used to start and control Maxima from within R by entering Maxima commands. It facilitates outputting results from Maxima in LaTeX and MathML. 2D and 3D plots can be displayed directly. This package also registers a knitr-engine enabling Maxima code chunks to be written in RMarkdown documents.
