Problems with loading ggplot2

I think the key message of the error message is there is no package called 'Rcpp' Rcpp is a dependency for ggplot2. It's saying when you try to load ggplot2, it can't because this dependency isn't installed yet. Some options: Just install the full tidyverse: http://tidyverse.tidyverse.org/#installation. This includes Rcpp. And reports to the console if there were any issues along the way. You could install Rcpp manually (and then you may have to repeat this process with each additional dependency.)
