NAMESPACE does not contain imports for RcppProgress

[elcortegano]

When the package I'm developing is built, a NOTE is returned for some OS (e.g. fedora-gcc-devel) indicating that:

Namespace in Imports field not imported from: ‘RcppProgress’
All declared Imports should be used.

Just recently I found out testing with rhub::check(platform = "fedora-gcc-devel") that this can be fixed simply by including import(RcppProgress) in the NAMESPACE. However, this is a NAMESPACE file generated with devtools::document() (a wrapper of roxygen2::roxygenize()), and it is meant to not be modified by hand.

This makes my wonder why RcppProgress was not included automatically in the NAMESPACE. Is this a bug?

Calls to RcppProgress in the package are not made in .R files, buy .cpp files, e.g.

// [[Rcpp::depends(RcppProgress)]]
#include <progress.hpp>
#include <progress_bar.hpp>
type my_function (args) {
    ...
}

You need to explicitly import it from the R code:

#' @import RcppProgress
NULL
