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);

+ int m=Rf_asInteger(n);//Rf_as*** is C API

+ List lst(N);

+ lst[0]=intvec;lst[1]=m;

+ return lst;

+ '

> as.test<-cxxfunction(signature(intx="integer",

+ n="integer"),

+ as.src,plugin="Rcpp")
