It is a recent feature of R itself, and comes from its Makeconf file -- in a well-intenioned-but-really-rather-cruel attempt to get rid of things like calls to assert(). But this also has side effects, so for RcppArmadillo we actually undo this at the bottom of RcppArmadilloConfig.h : // R now defines NDEBUG which suppresses a number of useful Armadillo tests // Users can still defined it later, and/or define ARMA_NO_DEBUG #if defined(NDEBUG) #undef NDEBUG #endif As for Andrew's earlier comment re | > Since RcppArmadillo was much slower than using STL vectors last time I tried | > it, I decided to benchmark Eigen before rewriting any code (see code below Could you try to demonstrate that with a quick example? I'd be surprised if it were generally true, outside of maybe a corner-case or unusual config you may have hit upon.
