[R] C-Code in R (running Windows)

[Liaw, Andy]

The simplest interface is to use .C() in R to call the C function.  The
details (with examples) are in the Writing R Extensions manual that comes
with every version of R.  To compile and load the .dll/.so into R, do:

- Type R CMD SHLIB file1.c file2.c  (at the command prompt, not the R
prompt)
-...start up R in that directory
- Type dyn.load("file1")
- You can now use .C() to call the function
