Install_extras not working?

I am writing an R package and am trying to use the feature .install_extras

described in Writing R Extensions . This document states that: "To install any other files in the vignette directory, include the vignettes / .install_extras file, which defines them as Perl-like regular expressions on one or more lines."

I created this file and contains the following line.

myfile.png

The png file is present in the vignette directory, but when I install the package using devtools::install()

, the file is not copied to the doc / install folder (or inst / doc of the development directory).

I've checked various packages on Github that use this feature (like Rcppzigguart ) and as far as I can tell, it should work.

Any ideas? This is with R 3.1.0.

Ok, I feel a little silly, but the problem is that install()

you need to manually before build_vignettes()

. This strikes me as intriguing: shouldn't you install

do whatever it takes to install the package?

I had a similar problem when trying to get the citations file bibliography.bib

located at vignettes/

copied to inst/doc

. This is necessary if you want to use the same quote .bib

file from other documents, such as README.Rmd.

The file is bibliography.bib

not automatically copied to inst/doc

during installation / build / reboot; you must explicitly declare the file .bib

in .install_extras

. Also, you need to run devtools::build_vignettes()

. The file .bib

will then be available in inst/doc

, which will be available to any document in the package using the following:

bib_file <- system.file("doc", "bibliography.bib", package = "myPkg")

...



I use it along with a package knitcitations

when I need to provide a source in a README or an example notebook.
