Hello. Is there a package or functionality available somewhere which will allow for complex searches (such as what SQL can do) of collections of RData files? Search capability within a given RData file at a time (which could be put in a loop) would be good, but the capability to perform joins to data across multiple RData files would be great. These queries might be ad-hoc, so writing an R program to get(load(...)) each file and customize the search in home-grown R code isn't feasible.

This shouldn't be dependent on environment details, but just in case: I'm running version 2.13.0 in a Unix environment (but could easily run in Windows too).

Thanks very much.
