I believe it is now recommended that a class to be exposed in a module
should expose a default constructor (i.e. a constructor called with no
arguments). Is such a constructor actually called or is it just there

CRAN mirror site and not the R-forge site. There are some issues with

My colleague Sunduz Keles once mentioned a similar problem to me. She

(both real-valued in her case) and she wanted, for each element of the
test sample, the proportion of the reference sample that was less than
the element. It's

Rcpp from SVN version 3004 is segfaulting on me in the unit tests at
test.sugar.asvector
Executing test function test.sugar.asvector ...
*** caught segfault ***
address 0x3, cause 'memory not mapped'
Traceback:

Sorry - I misspoke. The segfault was with R-2.13.0, the Ubuntu
maverick amd_64 build.

I have been facing this problem for months now and I still don't know

Oops. Scratch that theory. I don&#
Yesterday I upgraded to Ubuntu 11.04 for which the default g++ version is 4.5.2
I rebuilt R-devel and R-patched from the sources and things changed --
R-devel CMD check Rcpp now fails at a different point. This time it
doesn't segfault but it does produce results that are different from

OK, this is bizarre. I am able to install the RcppArmadillo package
on my current setup provided that I turn on optimization in the call
to g++ to compile RcppArmadillo.cpp. The only difference between the
following two calls is the -O3 flag. (I haven't tried other levels of
optimization yet but
And I can get past R CMD check Rcpp if I include -O3 in CXXFLAGS.

I'm working on translating Tim Davis's CSparse library of C functions
into templated C++ classes. The purpose is to allow spare matrix
manipulation both using Rcpp objects and using other types of vector
objects, such as std::vector.
The templates are in terms of the vector objects. The basic

You can check what is done in R itself in the R sources but I imagine that
it uses a uniform random variate converted to an integer through the
cumulative probabilities. The good news is that it is easy to create the
cumulative weights with the std::accumulate function.

I am developing classes for sparse matrices with an Rcpp interface that includes
Rcpp::Dimension dim() const {return Rcpp::Dimension(nr(), nc());}
Rcpp::NumericMatrix asmatrix() const;
The implementation of the asmatrix method begins with
Rcpp::NumericMatrix ans(dim(
Sorry for the long subject line but I hope it describes what I want to
do. I have a C++ class, dgTMatrix, that is exported in a module
definition.
RCPP_MODULE(RcppSp) {
...
class_("dgCMatrix")
...
;
}
Many of the methods for this class return other members of this class.
