Checking reverse dependencies: the tiny way
This article is originally published at http://www.markvanderloo.eu
The tools
package that comes with base R makes checking reverse dependencies super easy.
- Build your package tarball (the
pkg_x.y.z.tar.gz
file).
R CMD build /your/package/location
It is a good idea to make sure that the tarball is in a dedicated directory, because the next step will download and install reverse dependencies in the directory where the tarball resides.
- In an R terminal type
result <- check_packages_in_dir("/directory/containing/tarball"
, revdep = list() )
The result can be printed and summarized and analyzed further if there is any breakage. Here's an example of output when I ran this on my gower package today.
> result
Check results for packages in dir '/home/mark/projects/gower/output':
Package sources: 1, Reverse depends: 5
Use summary() for more information.
> summary(result)
Check results for packages in dir '/home/mark/projects/gower/output':
Check status summary:
ERROR NOTE OK
Source packages 0 0 1
Reverse depends 1 3 1
Check results summary:
gower ... OK
rdepends_ceterisParibus ... NOTE
* checking dependencies in R code ... NOTE
rdepends_lime ... ERROR
* checking tests ... ERROR
* checking re-building of vignette outputs ... WARNING
rdepends_live ... NOTE
* checking dependencies in R code ... NOTE
rdepends_recipes ... NOTE
* checking dependencies in R code ... NOTE
rdepends_simputation ... OK
(Checking the logs in output/rdepends_lime.Rcheck/00check.log
shows that lime
fails because of a missing JAVA engine [I just updated my OS and have no JAVA installed yet].)
Notes
- Checking reverse dependencies can be done in parallel by setting the
Ncpus
argument larger than one. - Be aware that the documentation states that (R 3.5.2) This functionality is still experimental: interfaces may change in future versions. Nevertheless, it has worked fine for me so far.
