gnu ODBC driver for ORACLE in WinXP platform?

I read on the ROracle pre-compiled binary README file that:

I do not have the software available this package depends on."
Why it is dangerous to use ROracle for windows?
What software does ROracle depends on in windows platform?
Is there a GNU solution for an

[LLVMdev] madandas@soe.ucsc.edu
Hello,
I'm trying to find if the access within a loop body is using the loop
induction variable, and to get the start and end indices of the loop.
for(int i = start; i < end; i++) { A[i] = 0; }
Let's say, I want to replace this with a function call 'zero(A,start,
end)'
How can I get the Value for start and end, and see if the index is same as
loop induction variable?

ORACLE SQL/ LEER DATOS EN R
Con oracle puedes usar, si tu máquina es de 64bits la librería Roracle que va muy bien y no es muy complicada de instalar.
Hay que distinguir 2 cosas, cuando accedes a la base de datos y allí haces la consulta, eso da igual si lo haces con RODBC o Roracle y cuando cargas los datos en tu data.frame, en esta operación, ya no está usando el gestor de base de datos sino tu propio R. La velocidad y
