Learn R Programming

Tools for Matrix Algebra, Optimization and Inference Problems

maotai is an R package whose name is an acronym for Matrix Algebra, OpTimization, And Inference problems - though I can’t deny motivation from one of my father’s favorite for the namesake. More detailed introduction will be added later.
