[R] ROracle error at step 1

Hello and thanks for the quick reply.

I got it here, 
	http://stat.bell-labs.com/RS-DBI/download/index.html

As the following site
	 http://cran.r-project.org/web/packages/ROracle/NEWS

mentions that the changes to the newest version are trivial. Although I
take your point that package could be expecting R code that has since
changed.

Whilst I can happily code in R the make file, Makefile.win,  for Version
0.5-9 is a bit beyond me. I'm not really a C++ expert. I don't suppose
you
or the wider R community have the binary for version 0.5-9? According to
the readme for the package

http://cran.r-project.org/bin/windows/contrib/r-release/ReadMe

"Building binary versions of the contributed packages on CRAN has been
automated. Binary packages will be available on CRAN about 1-3 days 
after the sources have been published."

But I can't find any. All I want to do is kick off a stored procedure in
an Oracle database, I think it might be easier to go through rJava. I
don't want to quite give up just yet, on the elegant direct approach.

Thanks in advance 
Sean

Where did you get your ROracle package from?

> Built: R 2.2.1; i386-pc-mingw32; 2006-02-13 18:05:59; windows

indicates it was too old.  All methods-using packages need to have been 
installed recently, and definitely since 2.4.0.  (It is unsafe to use
one 
that has not been installed for the same 'y' in 2.y.z because of its 
propensity for extracting bits of the R under which the package was 
installed.)

So 'step 1' is to install ROracle from the sources.
