Difficulty installing dev version of ggplot2 due to rlang::is_list not being found

[jcblum]

I don't know if these problems are related or not, but there's some talk of trouble with github ggplot2 (and rlang) over in this thread:

Issues with packages after updating to R 3.5.0

I got it to work by reinstalling R without the i386 files. rlang would install after I installed devtools from github, and I finally got ggplot2 to install from github after removing the i386 architecture, seems there's a build problem with ggplot2 on github right now
