Hello everyone,
For those of you who have used the sparse matrix capabilities of
Armadillo/RcppArmadillo, how seamless are the operations in moving between
sparse and dense matrices? I know there are some tricks for getting
sparseMatrix objects into SpMat objects (Dirk has a nice Rcpp Gallery
Davor,
I¹m not sure if this question is in reference to an email from Brian
Ripley, but I was under the impression that we should include Rcpp and/or
RcppArmadillo in Depends so that it is not installed for binary versions
of the packages. The following excerpt is from an email recently sent out

Hi Joshua,
I had the same problem a month or two ago. Try installing Rcpp from source.
(that did the trick for me)

Hello everyone,
I’m getting a weird error anytime I try to use a NumericMatrix in a function
compiled using the sourceCpp function. In case it matters, I’m running Mac OS
X 10.9.1.
I compiled a simple NumericVector function with no problem:
library(Rcpp)
src <- '
#include
using namespace Rc

I'm getting the picture now. Thanks for the additional example. And
Doug, sorry I still missed your earlier point.

I am doing some linear algebra on large matrices in R and receiving the
following error: "allocMatrix: too many elements specified". From what I
understand, the error is caused by the fact that R uses 32-bit ints and not
64-bit ints for matrix indices, so R doesn't have a way to represent all

Hello everyone,
I got flagged for the _ZSt4cout warning below on a recent CRAN submission of an
