It is a small class for iterative compositions. It looks like there's a
bad_alloc between the R and C++ sides of things but I'm not quite sure what
to check on it
Hi,
I feel guilty that I am a Windows user, and that I am using RStudio, both of
which is not welcome here. At least the latter is probably not guilty here.
Before looking at the details, I had reported it on the RStudio list, because I
thought it was a problem with roxygen.
To reproduce:

Can we leave the trolling out and concentrate on Rcpp isssues here?
This list has worked quite well
Dieter,
Try locating the roxygen right above the function you want to document
(rcpp_hello_world). If you do that then it will be placed next to that
function in the .R file (when you have "standalone" roxygen within a C++
file then it's automatically associated with a NULL object in the .R file).
Hi Rcpp devel list,
One of the functions I like to use is zoo’s rollapply() function. However
sometimes this can be slow as it is basically a long loop using mapply.
Given how fast loops are in C++ this seems like this would be the perfect thing
to covert into C++, BUT, one of the benefits of r

Hi Kevin,
I just had a quick look, at RcppRoll and noticed that almost all of the results
have a single value as an output, and was wondering if it was possible to be
able to get more than one output per loop…
to give a quick example, i would be grateful if you could show me how the

Unrelated, mostly, as it was a for loop with iterators using comparison

Possibly interesting results; at least to anyone who may typically
construct and populate a class in the constructor...

I just saw a tweet that said that support for Rcpp modules will be dropped in
"Release 11".
When will this occur?

This mailing list is about Rcpp -- whereas the tweet you refer to (if it was
the same one I saw) was about Rcpp
Rcpp11 is an alternative implementation of Rcpp indeed. It does not mean
discussing it is not suitable to this mailing list.
Rcpp11 will be released closely after R 3.1.0, whenever this happens to be. It
contains major improvements over Rcpp, will be completely header only (no src/
