Hello,
Is there a manual that describes how to convert from Rcpp types to
Armadillo/RcppArmadillo types and then back to R or Rcpp types?
Also, just to confirm, is matrix multiplication in RcppArmadillo
really as easy as C = A * B?
Thank you.

Yes, I have concluded that I will be using RcppArmadillo - I have
noticed that it is easier to use after read the RcppGSL vignette.

No,
I been planning to use RcppArmadillo to code packages intended for
release on CRAN. Following this discussion, it seems that I should
switch to RcppGSL because it does not have this function that causes
problems when compiling on Mac.

While hope does spring eternal, I see little chance for this.

Thank you for guidance, Dirk. My package with inclusion of symmatl() builds
and loads without issue under Windows using the Rtools toolchain for
R-2.13.1. Since my package must build on all platforms supported by R to
successfully upload to C-RAN, I will remove symmatl(). This may not be the

OS X is stuck at a known buggy version of g++, namely g++-4.2.1. Conrad has
some issues with that upstream, we mostly cope.
I just did a quick grep and symmatl() is defined in a short file
fn_symmat.hpp without any #define or #if statement, and that file is directly
included.

Hello again Rcpp experts, I asked my colleague to attempt an install on his
personal Macbook just to be sure he wasn't experiencing security issues at
work. Anyway, he now receives an easier-to-comprehend error message. Yet,

There are a couple of things:
* As far as I know, 'src' should not include a main() statement, nor
should it have #include statements (these can be added in the
'includes' argument in cxxfunction)
* The first argument in cxxfunction is sig. Since you don't supply an
explicitly named sig argument,

I wrote an function to check that you have a valid R development
environment (with help from Simon Urbanek) for devtools.
Hi,
And thanks for posting here.
