Shouldn't the default version of Rtools for R 4.2 be "42"?

[yutannihilation]

Sorry if I'm misunderstanding the code, but I guess currently "40" is chosen no matter the version is above or below R 4.2.

actions/setup-r/src/installer.ts

Line 41 in c00599c

core.getInput("rtools-version") || (version.charAt(0) == "3" ? "35" : "40");

We'll see if GitHub will switch to 4.2 on the VMs.

I think release already point to R 4.2 except for the Ubuntu runners, but it acquires Rtools40 (right?), which doesn't feel correct to me. In my understanding, it's unrelated to whether the GitHub switches to 4.2 or not. Am I wrong...?

R 4.2 works fine with Rtools40, which is pre-installed on on the VM. Installing rtools 4.2 would take several minutes and it does not have any effect for most people. You can already select rtools 4.2 if you want to install it.

If GitHub switches to Rtools 4.2 on the VM, then we'll of course use that, installing Rtools40 would not make much sense then.

Thanks. I really need Rtools42, not Rtools40, for testing the things where the subtle differences do matter, but I agree it's a rare case and I can keep specifying rtools-version: '42'. Closing now. Sorry for the noise.
