A few more thoughts based on a simple question: how do you determine the
length of a vector?
Rf_length() is used in example code in R-exts, but I don't think it's
formally documented anywhere (although it's possible I missed it). Is using
in an example sufficient to consider a function to be part

While I believe R Core is in the process of such clarification, I'd also
vote for this. Now that WRE has "experimental" category, and if we take the
current definition of

I just saw the recent commits about the "experimental" entry points. So, my
original question about the current status of ALTREP is now resolved. I'm
glad that ALTREP is confirmed usable on CRAN (with care). Thank you for all
your help!
I think other "non-API"s still need clarification. For

Hi Yutani,
The headers have been updated by Luke Tierney: ALTREP is an *experimental*
API, in that it is an official API that is legal for packages to use, but
may it change with short notice as the framework is further developed.
Hope that helps,

Thanks for your convincing comment, but it seems the R core team has a
different opinion...
A few hours ago, src/include/R_ext/Altrep.h got this comment:
/*
Not part of the API, subject to change at any time.
*/
commit:
Hi Yutani,
ALTREP is part of the official R api, as illustrated by the presence of
src/include/R_ext/Altrep.h. Everything declared in the header files in that
directory is official API AFAIK (and I believe that is more definitive than
the manuals).
The documentation of ALTREP has lagged behind
Thanks, Hernando,
Sorry, "API" is a bit confusing term in this context, but what I want to
discuss is the "API" that Writing R Extension defines as quoted in my
previous email. It's probably different from an ordinary sense when we
casually say "R C API".
You might wonder why I care about such a
Hello, I don't believe it is illegal, as ALTREP "implements an abstraction
underneath the C API". And is "compatible with all code which uses the API".
Please see slide deck by Gabriel Becker, with L Tierney, M Lawrence and T
Kalibera.
