The R source code, specifically src/main/names.c which maps the .Internal
named call to C calls. In your case the lines
{"dend", do_dend, 0, 111, 6, {PP_FUNCALL,
PREC_FN, 0}},
{"dend.window", do_dendwindow, 0, 111, 5, {PP_FUNCALL,
PREC_FN, 0}},
and
gannet% grep do_dend *.c
...
plot.c:SEXP do_dend(SEXP call, SEXP op, SEXP args, SEXP env)
plot.c:SEXP do_dendwindow(SEXP call, SEXP op, SEXP args, SEXP env)
(This might be better continued on R-devel, if it need continuing.)
