I'm trying to install ggplot2 but get the error message in the console. The message is like that:
Warning in install.packages : unable to access index for repository http://cran.rstudio.com/src/contrib: не могу открыть URL 'http://cran.rstudio.com/src/contrib/PACKAGES' Warning in install.packages :
Warning in install.packages : package ‘ggplot2’ is not available for this version of R
Have a look at
The error messages are the same.
This seems like a connectivity issue, R is not being able to connect to the CRAN repository you have selected, these are some things to try.
