[Rcpp-devel] nested lists into Rcpp

| Hi all,?
| 
| this is my first question here:
| 
| I have in R a list with several elements, some of them are lists, in the vein
| of this:
| 
| mylist <- vector("list",10)
| for(m in 1:10){
| ? mylist[[m]]$ID <- m
| ? mylist[[m]]$num <-?vector("list",5)
| ? mylist[[m]]$num2 <-?vector("list",5)
| }
| 
| Is there a way to pass a data structure like this to a Rcpp function, convert
| it to an appropriate C++ structure, and after doing some work with it, return
| it in its original form?
| 
| fun <- cxxfunction(signature(x='List'), plugin='Rcpp', body = ' ?
| ?using namespace std;
| ? List templist(x);
| ? //operations...
| ? return(wrap(templist));
| ? ?') ??
| 
| Surely I am missing something obvious here, but I am just arrived to Rcpp, and
| after looking in the documentation, I haven't found anything similar.?

There are working example in the RcppExamples packages -- and you need to
look at the C++ sources, obviously -- that do this.
