Venelin,
For completeness, things also work for me on conversion vectors 'in':
R> cppFunction("SEXP uvec2(arma::uvec v) { arma::uvec w = 2*v; return(wrap(w));
}", depends="RcppArmadillo")
R> uvec2(seq(1L, 3L))
[,1]
[1,] 2
[2,] 4
[3,] 6
R> cppFunction("SEXP ivec2(arma::ivec v) { arma::ivec w = 2*v; return(wrap(w));
}", depends="RcppArmadillo")
R> ivec2(seq(1L, 3L))
[,1]
[1,] 2
[2,] 4
[3,] 6
R>
A reproducible example would be good.
Dirk
