Just wanted to add a note, based on something I discovered elsewhere:
A new version of readr was released to CRAN approximately yesterday, and it appears that pre-compiled binaries for Windows are in a kind of weird, intermediate stage as far as availability. This means that if you tried to install tidyverse since yesterday, R may have tried to compile readr from source, which will fail on a Windows system where you haven't installed the RTools (a bunch of external compiler software).
It seems likely that this will resolve itself in the next few days as CRAN's gears finish turning, at which point a pre-compiled (= easy to install) binary of readr will hopefully once again become available for Windows!
Gory details for those who are curious...
