Hello, long time RStudio user really hoping for some quick help...
I am running macOS Catalina 10.15.1.
I tried installing some packages to do a multinomial probit regression (mlogit and MNP) and ran into the same errors: "Package which is only available in source form, and may need compilation of C/C++/Fortran: ‘statmod’".
After a bit of troubleshooting with no success, I decided to uninstall and reinstall all my packages, which caused more errors and then a repeating dialogue box asking if I wanted to re-start RStudio, which would never go away.
Then I decided to reinstall the latest version of RStudio. When I open it now, I get "This site can't be reached". I also tried an older version of RStudio, and I just get a white screen.
I am not sure if I messed something up with the packages I was installing, or if this is some other issue.
Thanks for any help!
