Greetings. I've been trying to get familiar with RcppArmadillo and RcppEigen.
As my "Hello, world!" example I'm using matrix multiplication. I got the
Armadillo version to work, but I'm having trouble with the Eigen version.
I'm trying to mimic one of Dirk's gallery snippets:

Greetings. I'm trying to go through some of the examples in the notes from
Dirk's Rcpp Masterclass of 28 April 2011. (I didn't take the class. I just
found the notes on the Internet. Please let me know if my use of them
violates some law or protocol. In case it makes any difference, I'm not

FWIW, the random-number stuff in C++11 appears to be greatly expanded:

Greetings. It appears that there is a limit of 20 items in a list created by;
Rcpp::List:create
I.e., the appended code works as expected if I omit all references to "x21",
but fails with an error (shown below, after the code example) when I include
"x21". (The successful output shown bel

Greetings. I need to return a list of initially-indeterminate length from
C++. I found the following note from Romain:
http://article.gmane.org/gmane.comp.lang.r.rcpp/69/match=push%5fback+list
that seemed to solve the problem.
I made what I thought were some minor tweaks to the example (us

Thanks, Darren. That worked well.

Greetings. I'm trying to pick off, in C++, one component, which is a matrix,
from an R list.
In the first appended example, starting with:
** A list containing a matrix
I pass a list from R to C++ and pick it off with a simple assignment
statement:
ccode = '
Rcpp::List l(l_R);
.

Greetings. I'm trying to bootstrap my way into Rcpp. I have the impression
that the "Sugar" extension to Rcpp allows one to use R syntax to run a
substantial subset of Rcommands within C++ (i.e., using native C++ code, not
calling back to R). If that's the case, I evidently have a gaping hole in
