I ran into a Rstudio not connecting R yesterday. Here’s what I saw:
Long story short — this command from here worked:
mv ~/.local/share/rstudio ~/.local/share/rstudio-backupHow did I break it down? Basically, storage overflow. I created three variables by seq functions, each has 100 double type numbers. Then I used rep to create all possible combinations. Then I did some calculations for each combination by mapply. I have to admit, using mapply and tidyverse package, which I recently got familiar with in a workshop, are super handy. So I didn’t bother to write a function to loop over everything, which I would do before I went to the workshop. Anyway, these whole operations broke down my R-studio – it was freeze. I decided to restart R session immediately, but ended up with the connection failure showing up.
What I have tried:
I restart my computer, didn’t solve the problem.
I went to troubleshot, checked virus or firewall, not working either.
I uninstalled Rstudio, same error page.
Found the link and command to create a backup, it worked. But when I tried to open an existed project, the error page reappeared.
Turned out I need to recreate projects to make things work. I didn’t even bother to reinstall packages! Totally amazed by Rstudio!!!
