You are not making it very easy to help you as you do not clearly say what you really want. Some things you talk about don't exist (ie "float matrix in R"), others make no sense (XPtr of Eigen::Map when the latter already is a proxy object). As for the question of persistence, the single simplest approach I often use it create a trivial class holding a member variable of the "thing" you want to persist (often a database or resource handle, could even be a honking bigmemory object and shared handle) whichI create in the constructor, or an init() function, and release in the destructor.
