[R-SIG-Mac] CRAN Checks for R-Release appear to use R-Devel

[Marc Schwartz]

Hi,

This is in reply to Simon's request that I post on this topic separately 
from Hans' prior thread on rlang related problems.

In the course of looking at a few CRAN packages for that thread, 
including my own, I noted on the CRAN checks page for each package, that 
the results logs indicate the use of "R Under development", rather than 
the current R release version.

Specific example:

The CRAN check page for rlang:

https://cran.r-project.org/web/checks/check_results_rlang.html

shows in row 10:

r-release-macos-x86_64  OK

If I click on OK to get the CRAN check log with the following URL:

https://www.r-project.org/nosvn/R.check/r-release-macos-x86_64/rlang-00check.html

noting that the above URL shows:

.../r-release-macos-x86_64/...

However, the log header shows:

"using R Under development (unstable) (2021-02-19 r80028)"

Thus, if I read correctly, while the link should be for the CRAN check 
results log for the package using R release (4.1.0), it appears to be 
using an R development version from February 19, 2021.

If I check the same R Release logs for Linux and Windows for rlang:

https://www.r-project.org/nosvn/R.check/r-release-linux-x86_64/rlang-00check.html

and:

https://www.r-project.org/nosvn/R.check/r-release-windows-ix86+x86_64/rlang-00check.html

respectively, both indicate:

using R version 4.1.0 (2021-05-18)

in the log headers.

If I check the rlang logs for other OSs on "r-devel", they indicate:

"using R Under development (unstable) (2021-05-20 r80347)"

Thus, a more recent development version of R from May 20, 2021.

So, perhaps naively, I would presume a configuration issue for the macOS 
binaries on CRAN.

Simon, does that clarify the point I was making in the prior thread?

Thanks,

Marc
