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
Rcppmanually (and then you may have to repeat this process with each additional dependency.) - And are you sure you worked through the troubleshooting suggestions here? https://stackoverflow.com/questions/31717850/error-package-or-namespace-load-failed-for-ggplot2-and-for-data-table/39525903
