Hmmm. This is definitely not right:
SETCADR(R_fcall, x);

Dear R-help,
how could I create an R call in C code using lang2 with 2 and more
arguments? I tried this code:
SEXP f(SEXP fn, SEXP rho)
{
SEXP R_fcall, x, y;
PROTECT(R_fcall = lang2(fn, R_NilValue));
PROTECT(x = allocVector(REALSXP, 1));
PROTECT(y = allocVector(REALSXP, 1));
You set the first argument to x and then to y. Why are you surprised?
