On Windows I use MiKTeX and TeXstudio. On Linux I use TeX Live and TeXstudio. I don't write much in LaTeX. I write a lot in R Markdown.
R Markdown output to pdf works best (for me) with TinyTeX LaTeX (vs MiKTeX or TeX Live). Can I still use TinyTeX to make TeXstudio run properly (and LyX too) for the occasional times I use those programs. Or do I need a 'proper' LaTeX such as MiKTeX or TeX Live?
