It's been a hectic week so this announcement comes a little late. Conrad
told me on Monday about his new minor release Armadillo 2.4.4 which I wrapped
into RcppArmadillo a day or two later; I think it got to CRAN on Wednesday or
Thursday. Incremental changes only, the NEWS entry is below.

Dear Prof Bates,
i have started to account for the difference
in performances between the cpp only and the
rcpp.
ctrl-f ing the rcpp docs does not give much
on manipulation of float. Is there a way, in
rcpp, to use the fact that some parts of the
algorithm are float-safe?

Dear Jared,
thank you on so many levels:

yes i'm comparing pur c++ and rcpp and yes this is the part of the code
that has the difference in timing --the rest of the code times roughtly

I don't have the answer to his question, but it looks like he's not
comparing R to Rcpp/C++ but rather "pure" C++ to Rcpp/C++. And the
suspect code he posted isn't doing anything obviously (to me) silly,
like repeatedly calling back into R (of course it would have bigger
problems trying to do that
