I'm just trying to simply install a package, and the whole thing is FUBAR. Worked fine earlier this week. Haven't touched firewall settings or anything, and have tried to install both "readxl" and "dplyr" (dplyr just to test if the problem was the readxl package) on two separate machines on two separate networks, with the problem persisting. Tried my home internet (both wifi and hardwire) as well as a mobile hotspot on my cell phone. How do I get it to go back to normal, with downloading and installing packages fast and easy?
> install.packages("readxl")

@Kevin, I selected the CRAN mirror in Michigan using chooseCRANmirror, but install.packages still defaulted to the original, bad mirror.

My default CRAN mirror has been updated as well, but doesn't seem to have an effect even after restarting RStudio.
***** Temporary Fix ***** This code must be run: a) after switching the default CRAN mirror and b) at the start of every session.

Try increasing the time out limit (maybe 300 will work instead of 100)
options(timeout=300)

Looks like it's a bug, with a CRANextra mirror baked into the RStudio options, pointing to an unstable destination. RStudio is reportedly aware of the issue, confirms it's a bug, and will fix on next release.
Default CRAN mirror must be changed first, then temp solution must still be run at the beginning of every session.
options(repos = getOption("repos")["CRAN"])

I ran into the same problem and have been working on it all day. I tried several different CRAN mirrors and finally this one worked:
install.packages('readxl', dependencies=TRUE, repos='https://ftp.ussg.iu.edu/CRAN/')
Downloads occurred instantly.
