Hi, I'm running RStudio behind a firewall on a Windows machine, without admin rights.
I succeeded in installing tinytex via tinytex:::install_prebuilt(), and compiling simple \documentclass{article}s works fine, but if I try to knit a Beamer presentation, tlmgr fails to connect to CTAN mirrors to download the missing beamer package (plus dependencies).
I suppose one could specify different proxy settings, but I'm lost from hereon onwards.
FAQ 14 on https://yihui.org/tinytex/faq/ recommends specifying proxy settings via a ~\.wgetrc file, but as far as I can tell, a Windows version of wget is not installed on my PC.
And even if there was, I simply wouldn't know how to specify those settings manually...
Any help would be much appreciated!
Edit: an issue has been filed at https://github.com/yihui/tinytex/issues/207.
Edit 2: The issue has been solved. install_prebuilt() now ships with a lot of useful packages by default.
