Using LaTeX in R Notebooks

If you check out the replication notebook for this week’s lab, you will notice dollar signs used around references to particular variables like this - $x_1$. This is your first exposure to LaTeX syntax. The dollar signs instructs LaTeX/knitr to enter “math mode”, which displays equations and mathematical notation. The underscore instructs LaTeX/knitr that the “1” should be treated as a subscript (i.e. “x sub 1”). Note that this does not look great when you look at the html output’s headers. So, it may take some experimentation to get it working perfectly.

Extra Information
