Hi would you please help me with this? No matter which version of R I install, it all says not availlable for that version. I was trying to install the package of "ggplot2" as well, the same problem. Thank you in advance.
Your problem is not with your R version, R is not being able to connect to the CRAN repository, is your internet connection behind a proxy server or firewall? That is usually the case when you are at work or school.
