In RStudio (Windows 10) using bookdown, I am unable to compile a PDF version of my book. I get an error message "mathspec.sty" file not found. I installed it on my MikTex folder, but the error persists. How to solve this?
Then, I tried to compile to pdfdocument. Now, I got errors from Latex because bookdown is unable to link to my preamble.tex file. How to make preamble.tex visible?
