I have installed the latest version of R on redhat machine but unable to install packages after it. It's taking a long time to choose appropriate cran option mirror to get install packages. Once I selected the cran mirror option and trying to install the packages but it showing me the error.
Same I have tried on RStudio server too but CRAN option mirror is not showing any options.
Warning: unable to access index for repository http://ftp.iitm.ac.in/cran/src/contrib: cannot open URL '<<link>>' Warning messages: 1: In download.file(url, destfile = f, quiet = TRUE) : URL 'https://cran.r-project.org/CRAN_mirrors.csv': status was 'Couldn't connect to server'
Issue 2) I have attached the screenshot of same.(RStudio server error)
Thanks and Regards,
