Take for example
$ \theta_{posterior} \leq -1.645*\sigma_{posterior}$ and $ \theta_{posterior} \geq 1.645*\sigma_{posterior}
$
It displays perfectly fine in the R Studio Viewer.
However, if I preview the file it merely displays text
{posterior} 1.645{posterior}
I thought R Studio had mathjax for rendering latex equations? Is there something else I need to install? All I can find online is in regards to installing MikTex for rendering pdfs.
