Build_vignettes and Latex Imports

The latest version of build_vignettes() in devtools causes LaTeX to be unable to find imported files (such as imported image file) placed in vignettes/ package folder. My earlier email posted to the devtools Google Group provides more details. A zipfile was also attached to that Groups post, with a simple reproduceable example.

Hi,

I'm a huge fan of devtools - well done, and thanks to Hadley!

I'm having an issue building a vignette with devtools build_vignettes() function. A reproduceable (I hope) example is attached.

I wish to import a pdf image into the pdf produced by LaTeX, via LateX's 'graphicx' package and the '\includegraphics' command.

The image.pdf file I have placed in the vignettes/ subfolder along with my .Rnw file - but with the latest version of devtools, LaTeX is no longer able to find the image file:

$%$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

require(devtools)

See the pdftex.def package documentation for explanation.

In addition: Warning message:

$%$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

I imagine I could specify a full path in my LaTeX file as a work-around, but this would surely cause problems if others try to rebuild the package from my source?

An earlier version of devtools did not have this issue. Is there a more appropriate place for me to put extra files like image/pdf, or can build_vignettes() be tweaked to allow LaTeX to find such files placed in vignettes?

Also, now that the vignette build is done in a temporary directory to avoid cluttering up the vignettes folder (nice!), I wonder if it would be helpful for build_vignettes to report the location of this temp directory, in case one wishes to check the log file produced by LaTeX (esp in case of LaTeX problems)?

I am using MiKTeX 2.9, devtools 0.8 and R2.15.1 (not, admittedly, 2.15.2)

Thanks

Alec

This is a problem because recent versions of devtools avoid leaving latex build artefacts in your latex directory. It does this by setting the latex working directory to a temporary directory, which obviously means it can't find your images. It might be better to use -output-directory=DIR rather than modifying the working directory.

Or even better (maybe) just do a fake/partial package install and copy back in, a la compile_dll
