Could you make some examples available for profiling?
It seems to me that there are some delicate licensing issues in distributing a product that writes .rda format except under GPL. See, for example, the GPL FAQ.

There is a recurring need for importing large csv files quickly. David Baird's dataload is a standalone program that will directly create .rda files from .csv (it also handles many other conversions). Unfortunately dataload is no longer publicly available because of some kind of relationship with Stat/Transfer. The idea is a good one, though. I wonder if anyone would volunteer to replicate the csv->rda standalone functionality or to provide some Perl or Python tools for making creation of .rda files somewhat easy outside of R.
As an aside, I routinely see 30-fold reductions in file sizes for .rda files (made with save(..., compress=TRUE)) compared with the size of SAS binary datasets. And load( ) times are fast.
It's been a great year for R. Let me take this opportunity to thank the R leaders for a fantastic job that gives immeasurable benefits to the community.
