[R] Large data sets and aggregation

I've noticed quite a few messages relating to large data sets bedeviling
R users, and having just had to program my way through one that actually
caused a "Bus error" when I tried to read it in, I'd like to ask two
1) Are there any facilities for aggregation of data in R?
( I admit that this will not do much for the large data set problem
2) Is there any interest out there for a C-based roll-your-own
I've had to reduce over 150,000 records to just under 3000 for a
multi-record per case data file, and I might be able to generalize the
code enough to make it useful for others.
