DBI/ROracle for remote database connection ?
Hello, I have installed the ROracle and DBI packages, and I want to access an Oracle database that is not on the same machine as the one I am running R on. I can access the database remotely with perl DBI and Java JDBC. Does anyone know if this is possible using R DBI/ROracle ? I have looked through the documentation and also tried to guess at things which might work, but with no success. I

database table merging tips with R
I have not devoted time to setting up ROracle since binaries are not available and it seems to require some effort to compile (see http://cran.r-project.org/web/packages/ROracle/index.html). On the other hand, RODBC worked more or less magically once I set up the data sources. What is your success using ROracle and why would it be preferable to RODBC ? -Avram On Thursday, September 11,

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.

consistent segfaults in ROracle with one of the databases
Dear list. Has anybody had any issues with ROracle, namely consistently leading to a segmentation fault? One of our oracle databases seems to have certain issues at the moment (do not know what exactly though) and if that one is queried ROracle definitely fails with a segmentation fault. Any ideas? Here is the trace and below is also a type of query that crashes it: *** caught segfault ***
