check_rev_deps: Check reverse dependencies

In checked: Systematically Run R CMD Checks

Check reverse dependencies

Description

Check a package's reverse dependencies in order to identify differences in reverse dependency check results when run alongside your package's development and release versions.

Usage

check_rev_deps(
  path,
  n = 2L,
  output = tempfile(paste(utils::packageName(), Sys.Date(), sep = "-")),
  lib.loc = .libPaths(),
  repos = getOption("repos"),
  reverse_repos = repos,
  restore = options::opt("restore"),
  reporter = reporter_default(),
  ...
)

Arguments

path	file path to the package source directory
n	integer value indicating maximum number of subprocesses that can be simultaneously spawned when executing tasks.
output	character value specifying path where the output should be stored.
lib.loc	character vector with libraries allowed to be used when checking packages, defaults to entire .libPaths().
repos	character vector of repositories which will be used when generating task graph and later pulling dependencies.
reverse_repos	character vector of repositories which will be used to pull sources for reverse dependencies. In some cases, for instance using binaries on Linux, we want to use different repositories when pulling sources to check and different when installing dependencies.
restore	logical indicating whether output directory should be unlinked before running checks. If FALSE, an attempt will me made to restore previous progress from the same output (Defaults to NA, overwritable using option 'checked.restore' or environment variable 'R_CHECKED_RESTORE')
reporter	A reporter to provide progress updates. Will default to the most expressive command-line reporter given your terminal capabilities.
...	Additional arguments passed to checked-task-df and run()

Details

Runs classical reverse dependency checks for the given source package. It first identifies reverse dependencies available in repos. Then, after installing all required dependencies, runs ⁠R CMD check⁠ twice for each package, one time with the release version of the given source package installed from repos and a second time with the development version installed from local source. Both ⁠R CMD checks⁠ are later compared to identify changes in reverse dependency behaviors.

Value

check_design() R6 class storing all the details regarding checks that run. Can be combined with results and summary() methods to generate results.
