Dear Dirk and JJ,
thank you very much for your replies. In the end a named vector is
enough for my purpose:
cppFunction(
'
NumericVector myVett(NumericVector x = NumericVector::create(0) )
{
if(x.size() == 0) x = NumericVector::create(_["a"] = 1.0, _["b"] = 2.0);
return x;
}
'
)

Hi Matteo,
The issue here is that the Rcpp attributes code that parses function
declarations isn't able to parse all syntactic forms of C++ but rather a
subset. The default argument parsing is able to handle scalars, strings,
and simple vector initializations but not more complex expressions like

Dear Rcpp users,
a very simple question: I have a function that has a Rcpp::List
among its arguments, and I would like to set a default values for
that List.
Unfortunately this code:
cppFunction(
'
List myList(List x = List::create(_["a"] = 1, _["b"] = 2))
{
return x;
}
'
)
raises the
