Devtools: namespace does not delete old information when @importFrom changes

Are you using the latest version of roxygen2? It should recreate the NAMESPACE file from scratch every time.

Yes, I am using roxygen2 v3.0.0

Are you sure you don't have another @importFrom x y elsewhere?

Nothing obvious, but seems like I must have something lingering where I don't expect it. I will keep searching; sorry to be a bother.

I am reopening this issue because I have been able to create a MWE that produces an error associated with @importFrom (though I am not entirely sure related to my original post).

I constructed a skeleton package with barebones files and only edited the help.R file, which is very simple:

#' @docType package
#'
#' @importFrom plyr ddply
NULL

When I call document(package_directory, clean = TRUE) (where package_directory is a variable holding the path to the package), everything works fine. Now, I change help.R to:

#' @docType package
#'
#' @importFrom plyr
NULL

and call document(package_directory, clean = TRUE), which causes an error, as expected:

Error in asChar(ivars) : 
  empty name in directive 'importFrom' in 'NAMESPACE' file

Now, lets go back and fix the help.R so it is back to the original:

#' @docType package
#'
#' @importFrom plyr ddply
NULL

When I call document(package_directory, clean = TRUE), I surprisingly still get the error I got when broke help.R. I would have thought it would have worked fine here because document ignores the NAMESPACE file.

An additional twist is that if instead of using document after breaking things, I use roxygenize, it works fine.

According to the roxygen documentation, "If you have a simple package, you can use roxygenise(), but for anything more complicated, I recommend that you use document()." So, why does document not work here but roxygenize does? And when should each be used?

As for versions, I am up to date:

Ah, the problem is that document() first needs to run load_all() to load the package, and once you've broken the namespace there's no way to load it. In this scenario I usually just undo the change in git.

delete the namespace file and do load_all() and then do devtools::docuement(). It should do the work.
