I see. I thought that INTEGER and its relatives did coercion too, but now
I see that is not stated anywhere.
Eg. REAL is first used in "Writing R Extensions" in 4.7.1 as in
REAL(ab) = 123.45
and I cannot find a discussion about what it does previous to that, or
In Rinternals header file, it says
/* Under the generational allocator the data for vector nodes comes
immediately after the node structure, so the data address is a
known ofset from the node SEXP. */
This does not mean much to me. Perhaps a short comment in the
documentation would be helpful, if not already present.
