Re: [Rcpp-devel] List of Lists to List of Vectors

You have a point about push_back being amortized constant. In my code I do everything with Lists, which may explain why I needed to preallocate them. Unfortunately I forgot the motivation for using Lists instead of std:vector, which I must have considered at some point. In fact if you look at this
