Microsoft R Open 4.0.2 and openSuSE
One reason for my sometimes growing respect for Microsoft is that they support (just) Microsoft R Open. Back in May 2019 they released version 3.5.3. It was a long time coming, but Microsoft just released Microsoft R Open 4.0.2.
In the nick-of-time, really. Theresa Graefe’s RTutor tutorial on synthetic models appears to rely on at least version 3.6 of R.
Microsoft R Open 4.0.2 and openSuSE Leap 15.2
I mainly use Microsoft R on Windows, but Linux has once again become my ‘daily driver’
for home use. Microsoft R Open does support SuSE Linux Enterprise SLES installation. To install on openSuSE Leap 15.2, I needed to change line 109 of the
elif [ "$OS_NAME" == "openSUSE" ]; then
Microsoft R Open CRAN snapshots
Normally, I think snapshots are a good idea to ease maintenance (though it would be more usable if Microsoft had a more regular update cycle…).
For some reason, the default CRAN mirror isn’t quite working the way it should be.

The problem can be ‘fixed’ manually after R starts with the commands:
r <- getOption("repos") r["CRAN"] <- "https://cran.microsoft.com/snapshot/2020-07-16" options(repos = r)
but a more permanent fix is by modifying line 23 of
r["CRAN"] <- "https://cran.microsoft.com/snapshot/2020-07-16" # RevoUtils::getRevoRepos()
