Operator `%>%` not available although imported

[grst]

I have a minimal R package

R/test.R
DESCRIPTION

with test.R:

#' @import dplyr
NULL

#' A simple exported object
#'
#' @export
my_object = c(2.0, 4.0) %>% mean()

and Imports: dplyr in my DESCRIPTION.

When I run

Rscript -e "library(devtools); document()"

I get the following error message:

Updating testpkg documentation
Loading testpkg
Error in c(2, 4) %>% mean() (from test.R#7) : could not find function "%>%"
Calls: document ... withr_with_dir -> force -> source_many -> source_one -> eval -> eval
Execution halted

Is that expected behaviour?

My understanding was that roxygen2 should write all imports to the NAMESPACE file, but it already fails before the NAMESPACE file is written, because a package is not loaded.

obviously, this affects any other function that is used outside a function() in test.R and is not limited to %>%.

Note

If I use

#' A simple exported function
#'
#' @export
my_function = function() {
  c(2.0, 5.0) %>% mean()
}

instead, everything works as expected.

Should work in the development version, although importing all of dplyr is ill-advised.
