Dear R-list, I am trying to import (all) frames from a Microsoft Access database as individual data frames in a fancy loop, but I'm having troubles figuring out how to use the 'sqlFetch' from the RODBS package in a loop (mostly because I can't figure out how to loop over elements (I came from stata) I would very much appreciate if anyone on the list could help me solve this

R connectivity to database
Hello, does anyone know how I would go about getting R to connect to OpenOffice's Base program (OOo's version of MS Access) such that I can retrieve data from the database and perform calculations and data analysis? I'm totally new to R and Base and I've looked at some documentation, but found only examples for R connecting to PostgreSQL and MySQL, but nothing for OOo's Base

BackgrounDRb version 1.0RC1 available now

This new release of BackgrounDRb is also modular and can be used
