R markdown doen't work. Problems whit latex route.

[cruddy]

Hi! I don't know why, but even the markdown example of r studio doesn't work on my windows.
But latex by itself, works well (outside of R).
Does anyone have an idea? help please!

! Sorry, but C:\Users\crudd\AppData\Local\Programs\MiKTeX\miktex\bin\x64\pdflatex.exe did not succeed.

! The log file hopefully contains the information to get MiKTeX going again:

!   C:\Users\crudd\AppData\Local\MiKTeX\miktex\log\pdflatex.log

As your are using MikTeX, it is possible that you are missing a LaTeX package for your document to compile.
tinytex won't be able to automatically install missing package with MikTeX.

It will with TeX Live though which you can get by installing TinyTeX:

1.2 Install LaTeX (TinyTeX) for PDF reports | R Markdown Cookbook

This is a portable distribution that works well with R and R Markdown.

If you want to still use MikTeX, you can try to check in MikTeX log if any what package could be missing. Maybe tools like this package can help

GitHub - njtierney/chaletex: Tools to extract latex packages from a .tex file...

I would advice to install and use TinyTeX if you could: TinyTeX - A lightweight, cross-platform, portable, and easy-to-maintain LaTeX distribution based on TeX Live - Yihui Xie | 谢益辉
