[Rcpp-devel] DataFrame::create() in endless loop

Hi,

thanks everyone for the help,
I used IntegerVector and friends, 
and changed from DataFrame to List.

Thanks,
Steffen
It's a memory problem from R.  It is trying to do garbage collection

(RunGenCollector) and getting hung up, probably because of
exhausting

one of the stacks in R.  Your std::vector<int> objects need to be

copied to R objects.  Is it possible to define them as
IntegerVector's

instead, in which case the Create method will (I think) just move
some

pointers around.

I had the same problem a while ago and the solution we?ve come up with
was to get rid of Rcpp::DataFrame and use Rcpp::XPtr instead.

It turned out that Rcpp::DataFrame is rather impractical for
sufficiently large data sets. 

As an alternative, Rcpp::XPtr is a little bit more complex to
implement but by far more reliable and efficient.

For more details see this
http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2012-January/003335.html and subsequent messages.

Hope this helps.

Cheers,

Slava Mazur
