拿了去年R会议东东学习，中国科学技术大学的黄金山干货，遇到些问题，如下：
> as.src<-'
+ std::vector<int>intvec=as<std::vector<int>>(intx);
+ //wrong way!std::vector<int> impvec(intx);
+ int N=as<int>(n);

+ List lst(N);
+ lst[0]=intvec;lst[1]=m;
+ return lst;
+ '
> as.test<-cxxfunction(signature(intx="integer",
+ n="integer"),
+ as.src,plugin="Rcpp")
