I don't know of any native xls read/write facility in R, either in core or as add-ons (I could be wrong), but if you want some source code to scavenge on to build some R package out of it, there are two perl modules, Spreadsheet::ParseExcel and Spreadsheet::WriteExcel which are small enough to "read from front cover to back cover", so to speak, might be useful for reference and steal code from.
The other open-source packages which can read/write excel files are gnumeric and openoffice and probably too big to find one's way around the source code to steal there :-). Good luck.
