Hi, for your analysis use the package:
ROracle Oracle database interface for R http://microarrays.unife.it/CRAN/src/contrib/Descriptions/ROracle.html see also: Diego Kuonen, Introduction au data mining avec R : vers la reconquête du `knowledge discovery in databases' par les statisticiens.

Best Vito You wrote: Deall all, We need to perform a statistical analysis of a large database (40,000 entries with approximately 500 fields in each entry) currently handled in Oracle. The data contains categorical variables only. At the current stage we suggest classification and clustering analysis. We are planning to perform the analysis in R and would be very grateful for any recommendations/suggestions/references regarding the packages/tools appropriate for this task. Thank you in advance for your attention, Vicky Landsman ===== Diventare costruttori di soluzioni "The business of the statistician is to catalyze the scientific learning process." George E. P.
