-\subsection{Can I use default function parameters with \pkg{Rcpp}?}
-
-Yes, you can use default parameters with \textit{some} limitations. 
-The limitations are mainly related to string literals and empty vectors.
-This is what is currently supported:
-
-\begin{itemize}
-\item String literals delimited by quotes (e.g. \code{"foo"})
-\item Integer and Decimal numeric values (e.g. \code{10} or \code{4.5})
-\item Pre-defined constants including:
-\begin{itemize}
-\item Booleans: \code{true} and \code{false}
-\item Null Values: \code{R_NilValue}, \code{NA_STRING},
-\code{NA_INTEGER}, \code{NA_REAL}, and \code{NA_LOGICAL}.
-\end{itemize}
-\item Selected vector types can be instantiated using the empty form of the
-\code{::create} static member function.
-\begin{itemize}
-\item \code{CharacterVector}, \code{IntegerVector}, and
-\code{NumericVector}
-\end{itemize}
-\item Matrix types instantiated using the rows, cols constructor \code{Rcpp::<Type>Matrix n(rows,cols)}
