I am looking for a way to generate .Rout.save files for vignettes.
The manual "Writing R Extensions" states here [1] in item number 20:
"If there is a target output file .Rout.save in the vignette source
directory, the output from running the code in that vignette is compared
with the target output file."
Yet, there is no pointer on how to get the correct .Rout.save files for
vignettes. (For the files in directory "test" there is a footnote on how
to get the .Rout.save files. [2])
I agree, this should be documented. But it is rather easy:
Just create an empty file and call it vignette.Rout.save. Run the
checks, and you'll get lots of errors because it won't compare to the
real output.
When you get a compare failure, the file vignette.Rnw.log will be left
in the *.Rcheck directory. You can just copy that into the
vignette.Rout.save file.

As a temporary solution, we currently use a script that calls
tools:::.run_one_vignette() on each vignette and dumps the output:
echo 'tools:::.run_one_vignette("vignette.Rnw", docDir = ".");' | R
--vanilla > vignette.Rout.save
However, this doesn't result in the same code as produced by R CMD
check. E.g., we get the R startup header and furthermore get the output
in German where localization is available (thus having differences when
running R CMD check).
Does anyone have any hints on how to automatically get the correct
results (i.e., without the header)? And is it possible to include these
hints in the "Writing R extensions" manual for other users?
Any help is highly appreciated.
Best,
Benjamin
