Assume a C program invoked by .Call, that returns a list.
Near the top of the program we allocate space for all the list elements. (It is my habit
to use "xyz2" for the name of the R object and "xyz" for the pointer to its contents.)
PROTECT(means2 = allocVector(REALSXP, nvar));
means = REAL(means2);
PROTECT(u2 = allocVector(REALSXP, nvar));
u = REAL(u2);
PROTECT(loglik2 = allocVector(REALSXP, 2));
loglik = REAL(loglik2);
PROTECT(rlist = mknamed(VECSXP, outnames));
Can I assign the individual elements into rlist using SET_VECTOR_ELT at this point, or do
I need to wait until the end of the program, after I've filled in means[i], u[i], etc.? I
likely depends on whether I'm assigning a pointer or a copy.
