This releases owes a big Thank you! to Miguel Lechón who not only noticed errant behaviour and occassional segfaults with overly long commands sent to the embedded R, but even traced it to an oversight of mine in a simple memory buffer class and provided the one-line fix to reset a pointer! Much appreciated, especially as I got his mail two days before I talked about Rcpp and RInside at UseR! 2009 . The other changes are mostly cleanups, additions of two more test examples (to replicate the bug report) and some minor additions of a few new assign() functions to pass data between C++ and the embedded R session.
