R packages reinstalled



I should only need to install the R packages once unless I update my R version. However, after I install the packages in RStudio, close it and open it next time, I need to reinstall many packages that I have installed before. Some packages are saved, but I have to reload many others. I really want to know why is that and how to solve this problem. I do not want to reinstall packages every time.

Thank you!


Hi! Welcome!

You're right, that shouldn't be happening! I think it's going to take some more information to diagnose what's going on. Can you try the following?

  1. Try to install one of the packages that keeps needing to be reinstalled
  2. Copy and paste here all of the output you get in the console (if the forum software complains that it's too long, you can also post it as a GitHub gist or Pastebin paste and post the link)
  3. Copy and paste here the results of running sessionInfo() and RStudio.Version()
