[Rcpp-devel] warning from Rcpp gallery 'sample' implementation

[Ben Bolker]

Using the amazingly useful

http://gallery.rcpp.org/articles/using-the-Rcpp-based-sample-implementation/

I get a bunch of compiler warnings (copied in full below); the crux seems
to be

typename T1::elem_type = double; arma::uword = unsigned int]’ is deprecated

   I could dig in and try to fix this myself but feel like it might be a
deep rabbit hole for me ...  This is not critical, but it would
certainly be nice to have my code compile clean.

  (I'm happy to report this elsewhere if there is a more appropriate venue.)

 Also, FWIW, I get

lists.r-forge.r-project.org uses an invalid security certificate. The
certificate is only valid for the following names: *.r-project.org,
r-project.org Error code: SSL_ERROR_BAD_CERT_DOMAIN

  when subscribing to the list ...

 Any help appreciated ...
