This package contains a set of comprehensive syntax definitions for the R language. You don't have to install this if you already have R-Box installed as R-Box is shipping with a copy of R-Extended.

R-Extended support Roxygen, Rcpp, R Sweave and R Markdown syntaxes.

The R Markdown syntax is derived from Markdown Extended. LaTeX syntax is supported in R Markdown. For example

- $a$ and $b$ are variables such that
$$ 
a^2 + b^2 = 1
$$

Note: The dollor sign $ is treated as a special char, to display the original dollor sign $, please type \$.
