Hello, I am unable to install any packages on R studio. I also tried installing the zip files but in vain. I would appreciate any help. This is the error message
Are you able to load https://cran.rstudio.com/src/contrib in a web browser? Are there any firewalls or other internet filtering in place that could be blocking your connection to that address, or causing it to take a very long time to load? (it should load in a web browser in a few seconds or less, even over a relatively slow connection).
