Something I didn't emphasize before is that embedding R inside D 
does more than open the door to mixing R and D code together in 
one program. We now have an interface available in D to any 
compiled C, C++, or Fortran library for which there is an R 
package. You can call those libraries from D, no glue code 
required and using the existing documentation for the R package, 
yet it's fully efficient because you're passing a pointer to the 
data from D into the underlying library. R code only gets in the 
way (i.e., slows your program down) if you want to run functions 
written in R.
