Rmarkdown not rendering through Shiny solution

[syzdekbr]

I believe I have identified what caused the problem in this issue and a solution. I can see in the OP's post error message "Warning: Error in : LaTeX failed to compile C:\Users\MLEONA~1\AppData\Local..." that his user name is being truncated and replaced with "~". I experienced the same issue. A solution was to shorten the name of the subdirectory of Users directory. I don't know how short it needs to be, but I made it 8 characters and it no longer shortened it and I was able to render Rmarkdown from Shiny.

Hopefully that is helpful to others. I searched for an answer for a long time and it appeared others were stumped by the issue in that issue report, so perhaps adding above information will help others.
