packrat::clean and packrat::restore functions fail due to ignored packages

[markusdumke]

Hi,

I came across some errors with the packrat::clean and packrat::restore functions when working with ignored local packages.

I have a local R package included in my repository and added it to the ignored.packages. Then I have installed it with packrat::install("mypackage").

Then packrat::clean() will fail with the error message:

Error: Unable to retrieve package records for the following packages:

• "mypackage"

I have debugged the source code and found that a simple change in packrat:::unused_packages will fix it:
orphans <- setdiff(orphans, c("manipulate", "rstudio", packrat::opts$ignored.packages()))

Can you explain why you did not choose to ignore the packages listed in ignored.packages here? Though it might be strange that the package is listed in orphans though it is still in use. Maybe that is the point where something goes wrong? Happy, if you can help!

The same issue holds with packrat::restore.

I am using packrat 0.5.0.

Thanks for the bug report + diagnosis. This was likely just an oversight.

packrat::snapshot() works well with packrat::opts$ignored.packages("stat.desc") but packrat::restore() doesn't work.
stat.desc is my own package. I must move stat.desc, make restore then copy again package stat.desc inside packrat...

Error: Unable to retrieve package records for the following packages:

• 'stat.desc'
