The best way to use R's linear algebra functions from C
...uot; and a bunch of other things from the web, ran the
"Embedded" tests, and grep'ed / looked at the source code.
It is now my understanding that there are several ways I could use R from C:
1. Pass data from C to an R function, loaded during R runtime;
2. Build R statements and use Rparse.h to execute them;
3. Use Rembedded.h to call R's C functions;
4. Directly call R's C functions.
4) would be the fastest (I think?), and speed is some concern.
However, I am finding it very tough going to discover how to implement
this. For example: given two matrices represented as arrays...
