This works for me

// [[Rcpp::plugins(cpp11)]]

// [[Rcpp::depends(RcppArmadillo)]]

#include <RcppArmadillo.h>

// [[Rcpp::export]]
arma::vec foo() {
    arma::vec x = { 1.1, 2.2 };
    return x;
}

via

R> sourceCpp("/tmp/arma11.cpp")
R> foo()
     [,1]
[1,]  1.1
[2,]  2.2
R>

so I see no issue here.

In packages, you can use src/Makevars* (or DESCRIPTION). In files you have the plugin.

from rcpparmadillo.
