> What is a `"logically"-widened alwaysinline wrapper for the vector function`? Can you provide an example? Also, what is the `tricky processing` you are referring to that the vectorizer should care about?

Hi, all I didn't get any response from swig for my question. see if I can get some help here Thanks ---------- Forwarded message ---------- From: charlie <charlie.xia.fdu@gmail.com> Date: Tue, Nov 4, 2008 at 1:55 PM Subject: SWIG with R and C++ STL To: swig-user@lists.sourceforge.net Hi all, I am new to SWIG. I encountered some problem when I try to SWIG to R some C++ modules. Here

I'm a newbie for R lang. And I recently came across the "Recycling Rule" when adding two vectors of unequal length. I learned from this tutor [ http://www.r-tutor.com/r-introduction/vector/vector-arithmetics ] that: """""" If two vectors are of unequal length, the shorter one will be recycled in order to match the longer vector. For example, the
