I have a comment related to this post:
When I run install.packages() on Ubuntu, every package needs to be built from source.
Is this true for Red Hat as well?
Windows and MacOS have package binaries, which greatly reduce the amount of time for package installation.
Imagine if I had an Ubuntu server and I wanted to install 1,000 packages and each package took 5 minutes to build: (5* 1000) / 60 = 83. We're talking about 83 hours of build time (> 3 days)!
