Title: Update Profiling.rmd

I guess this is what you mean rather than the original. Typos are fine. A bigger problem would be if your code didn't work. In graduate school, I took a seminar covering "The Foundations of Factor Analysis" by Stanley Mulaik, and we caught 99 errors (mostly equations) in that book. At least 99 math errors makes understanding any derivations really difficult.
