[R] R-code in Latex --- $ sign causes error

The $ is special in TeX/LaTeX as a shortcut for beginning/ending inline math mode, so if you want an actual $ then you need to escape it so that the TeX/LaTeX file has \$ in it. This means that in your R code that generates the file you may need \\$ or in some cases \\\\$.
Hope this helps,
