Particularly relevant is Appendix A.6 of the Green book. The index isn't particularly helpful finding it. Of course, Appendix A can't answer the question of how the R implementation might differ. For example, A.6 discusses GET_SLOT_OFFSET, which does not appear to be available in R. Thanks for the pointers. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
