You don't want to be down at the C level, most likely: it would be much more straightforward and programmer-efficient to use one of the available bindings to one of the available open-source databases. R has useful / usable bindings to postgresql, sqlite, and mysql, among many others. These are, however, more generally useful when you reach the point that you simply can't manage the volume of your data in R objects or in data frames. [And, well, you can go a LONG way with intelligently named R objects. :-)] --elijah ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
