[R] Implementing R through Oracle

[Don MacQueen]

If it were me, I think I would try to use Rscript. R will still have 
to pull data using ROracle, and write back to Oracle, but the 
operation will be under the control of the pl/sql script.

A standard R installation now includes Rscript. Rscript is intended 
to be used, as I recall, in a manner analogous to perl or any other 
typical scripting language. That is, create a file whose first line is

   #!/path/to/Rscript

and that contains R code, including the use of ROracle. That script, 
if marked executable, can be executed from the command line. So if 
pl/sql can execute any arbitrary script file, then you can execute R 
from within a pl/sql script.

I'm describing a unix (Linux, Mac OS) type environment. Windows is 
foreign territory to me.
