R error: install.packages

I'm just trying to just install the package and it's all FUBAR. Worked well earlier this week. Didn't touch firewall settings or anything else and tried to install both "readxl" and "dplyr" (dplyr to check if there was a problem with the readxl package) on two separate machines on two separate networks, and the problem persists. Tried my home internet (both wifi and hardwire) as well as mobile hotspot on my cell phone. How can I get back to normal by downloading and installing packages quickly and easily?

@Kevin, I chose the Michigan CRAN mirror using selectCRANmirror, but install.packages still doesn't match the original bad mirror.

My CRAN mirror is up to date as well, but it doesn't seem to work even after restarting RStudio. Current CRAN mirror by default

***** Interim fix ***** This code should be run: a) after switching the default CRAN mirror and b) at the beginning of each session.

options(repos = getOption("repos")["CRAN"])

I faced the same problem and have been working on it all day. I tried several different CRAN mirrors and finally it worked:

install.packages ('readxl', dependencies = TRUE, repos = ' https://ftp.ussg.iu.edu/CRAN/ ')



Downloads happened instantly.

Looks like a bug, with CRANextra mirror baked into RStudio options pointing to an unstable destination. RStudio is reportedly aware of the issue, confirms the bug and fixes the next version.

The default CRAN mirror must be changed first, then the temp solution must be executed at the start of each session.

options(repos = getOption("repos")["CRAN"])
