Issues with knitting a PDF in RMarkdown

[Jehrenberg]

I'm having some issues with getting RMarkdown to knit to a PDF. I have installed and updated MiKTeX/followed the troubleshooting guide at https://yihui.org/tinytex/r/#debugging.

I have pasted the log pdflatex log with the error/warning/fatal codes below. I'm not quite sure what I'm doing wrong at this point and would appreciate any help.
Thank you
