Hi, I am using R studio for the first time to learn the program.
I was trying to import file from spss or excel and got this message:
unable to access index for repository https://cran.rstudio.com/src/contrib:
cannot open URL 'https://cran.rstudio.com/src/contrib/PACKAGES'
R probably looked for additional package to download and couldn't do it. Why?
Thanks in advance.
This could mean you can't access internet from your R installation.
Do you have a proxy or some firewall restricting internet access ?
What did you try exactly as command to get those errors ?
Thanks.
Finally I found the solution: I changed CRAN packages source from default to other from the list and R succeed to download all needed packages.
Glad you found a solution !
