  state = NULL,
  method = NULL,
  status = c("active", "revoked", "completed", "all")

codes (e.g. \code{"NSW"}, \code{c("VIC", "QLD")}) to filter on. \code{NULL}
returns projects across all states.}

\item{method}{Optional character vector of method name

\code{"completed"}, or \code{"all"}.}
}
\value{
