Outreg2 and Frmttable Variable Names Not Compatible with LaTex?

[Aja Kennedy]

I'm having issues passing my variable names to tables in a way that LaTex can read (without me manually making edits to the .tex output). I am having this issue both with regression tables (that I export using outreg2) and with summary stats tables that I create using frmttable (both user-written packages). Specifically, I thought outreg2 should automatically insert a "" before underscores in variable names when exporting to a .tex file, but I'm not finding that to be the case when I run my code. I'm an example below. For me, this code produces a .tex file that includes variable names such as "pct_black" without inserting a "" to before the underscore character. If anyone has an idea of what the issue is or how to fix it, please let me know!

Thanks.

outreg2 is from SSC (FAQ Advice #12). Why do you expect quotation marks before an underscore? In LaTeX, you want a backslash before the underscore for it to be rendered correctly, and that is exactly what you get.
