Reverse dependency tools.

Tools to check and notify maintainers of all CRAN and Bioconductor packages that depend on the specified package.

Usage

revdep(
  pkg,
  dependencies = c("Depends", "Imports", "Suggests", "LinkingTo"),
  recursive = FALSE,
  ignore = NULL,
  bioconductor = FALSE
)

revdep_maintainers(pkg = ".")

Arguments

pkg

Package name. This is unlike most devtools packages which take a path because you might want to determine dependencies for a package that you don't have installed. If omitted, defaults to the name of the current package.

dependencies

A character vector listing the types of dependencies to follow.

recursive

If TRUE look for full set of recursive dependencies.

ignore

A character vector of package names to ignore. These packages will not appear in returned vector.

bioconductor

If TRUE also look for dependencies amongst Bioconductor packages.

Details

The first run in a session will be time-consuming because it must download all package metadata from CRAN and Bioconductor. Subsequent runs will be faster.

See also

The revdepcheck package can be used to run R CMD check on all reverse dependencies.

Examples

if (FALSE) {
revdep("ggplot2")

revdep("ggplot2", ignore = c("xkcd", "zoo"))
}
