Hi R users and Dr. Uwe Ligges:
I read on the ROracle pre-compiled binary README file that:

Why it is dangerous to use ROracle for windows?
What software does ROracle depends on in windows platform?
Oracle (just like every other platform)! I believe the statement is
out-of-date: ROracle seems not to build with current versions of R. But

Indeed, the statement is out of date. I haven't tried to build it for
years now. Will change that part of the ReadMe.
Thanks to Brian for the comprehensive answer.
Best,

(a) It needs to link against Oracle's client software, and that depends
on the particular version of Oracle. Bitter experience suggests that
you need to build such packages from the sources against the client
software installed on your machine to get reliable service from them.
(b) The package does no actual tests in its examples. It may appear to
build but not work in practice, since nothing is tested in the build
process.
Is there a GNU solution for an ODBC driver on windows XP platform
for ORACLE for use it with RODBC?
What does GNU have to do with this? RODBC works with Oracle with
Oracle's own Windows drivers, and a test suite for Oracle is in the
sources. Now, that has been tested against only a couple of versions of
Oracle, but ODBC is a well-documented API and Oracle's ODBC driver
writers should always be complying with it.
If perchance by 'GNU' you meant 'GPL' or 'Open Source' then
- Oracle is proprietary, although there are 'free as in beer'
versions.
- the most open you can be is to communicate with it via an open API,
and ODBC is such (and I think the only one supported by Oracle).
Thank you for your help.
It does seem churlish to be asking why the hard-working volunteers have
*not* provided you with a binary version of a package, and such queries
are more common than thanks for those that *are* provided (something
like 20x as many).
