Thanks. Looks like I have some more reading to do. I did know
about embedr, but I saw it had dependencies and I wanted a
standalone and fully transparent D solution.
It requires an R package if you want to call D functions from R.
You need to link to R itself if you want to do something like
pass a vector from R to D and then access that data from D. Since
R is aware of the location of all the underlying libraries, it's
easiest to let it generate the dub.sdl for you.
I guess you're using the older .C interface [as done
here](http://users.stat.umn.edu/~geyer/rc/). Good enough if
passing double* and int* pointers to D functions will suffice.
Only thing you need to do to initialize the D runtime is add this
to your D code
```
struct DllInfo;
extern(C) void R_init_libfoo(DllInfo * info) {
Runtime.initialize();
}
```
where foo is the name of the library you're loading (foo.so).
