Emne: [R] R & very large files

I very recently started using R (as in: last week) and I was wondering if anyone could point me to website(s) with sample code to deal with large datasets (length- and/or breadthwise). I understood that R was never designed to work with datasets larger than, say, a couple of hundred Mb. One way is (as I also read) to let R work in conjunction with SQL. That's one interesting approach I'd like to know more about. But I was also hoping that there also were pure R solutions for working with very large tables (was 'scan' designed for that?). In any case, a standard approach would be desirable.
Thanks in advance.


In the face of ambiguity, refuse the temptation to guess.
