[R-pkg-devel] New API in R-devel & minimum version of R

[Michael Chirico]

data.table is doing the same in a number of places, Ivan even went so far
as to pin down a specific SVN commit for those as well:

#if R_VERSION < R_Version(4, 5, 0) || R_SVN_REVISION < 86702
#  define isDataFrame(x) isFrame(x) // #6180
#endif

https://github.com/Rdatatable/data.table/blob/0909048017d35f8b8a910c74549650f5de5a74a9/src/data.table.h#L21-L23

Sneaking onto my soapbox to complain that it really seems incorrect that R
CMD check started complaining about these issues before the API-compliant
functions were included in an R release. I was really surprised to see
these functions were not included in the most recent past release, for
example.

Anyway, 4.5.0 is due for release in a few weeks so this will become moot
momentarily.
