NOTE: Markdown does not support well for mathematical equations. And some equations not displayed properly in this page, such as $\frac{x}{y}$, $\sqrt[y]{x}$ and $\prod_{i = 1}^{n} x_i$, . See the html vignette for all the correct displayed equations.

Tools for converting R expressions to latex mathematical equations. This project is scratch from the section 21.3 transforms mathematically R code into its LaTeX equivalent.
