-----Original Message----- From: rcpp-devel-boun...@r-forge.wu-wien.ac.at [mailto:rcpp-devel-boun...@r-forge.wu-wien.ac.at] On Behalf Of Romain Francois Sent: Monday, October 21, 2013 8:33 AM To: rcpp-de...@r-forge.wu-wien.ac.at Subject: [Rcpp-devel] feature proposal: ListOf Hello, Another thing I have developped in dplyr but might be generally useful is the ListOf class. See https://github.com/hadley/dplyr/blob/master/inst/include/tools/ListOf.h The idea is to embed, by means of the template parameter what this list contains. Of course it is only usable if the list contains only objects that are compatible with the type. So if we knew we had a list of numeric vector, we could use : ListOf<NumericVector>, or ListOf< std::vector<double> > so that when we use LisOf extracting operator, we know what we get. This is something I've shared a few times on mailing list and SO, but could be generally useufl for Rcpp users. Do people want to see this in Rcpp. This is orthogonal to everything else, so the risk is minimum. This is a template class, so the cost is null if the class is not used.
