Calling primitive functions from C code
Does anyone have an example of calling primitive or internal functions from
C code that they would share with me?
I am having trouble trying to figure out how to construct the proper
arguments to pass to "do_subset_dflt"
Here is the prototype:
SEXP do_subset_dflt(SEXP call, SEXP op, SEXP args, SEXP rho);
The R_FunTab from "names.c" gives some additional information on the
arguments that the function expects.
{".subset", do_subset_dflt, 1, 1, -1, {PP_FUNCALL,
PREC_FN, 0}},
However, th...

Intermittent crashes with inset `[<-` command
The following code crashes after about 300 iterations on my?x86_64-w64-mingw32?machine on R 3.5.2 --vanilla.??
Others have duplicated this (see?https://github.com/tidyverse/magrittr/issues/190?if necessary), but I don't know how machine/OS-dependent it may be.??
If it doesn't crash for you, please try increasing the length of the x vector.

how to interpose my own "[" function?
...e stock R "[", does some additional work,
and then finally returns the modified result.
But, how do I properly call the stock R "[" function? It takes a
varying number of positional arguments, and its R-level closure is
just: .Primitive("[") It's implemented by do_subset_dflt in
src/main/subset.c.
The only thing I've come up with so far is using eval after crudely
re-constructing the original incoming call (example below), which is
both very slow and gets some of the semantics wrong.
Is there some good way for my function to just say, "take ALL my
incoming ar...
