R: Reverse dependency tools.

revdep {devtools}

R Documentation

Reverse dependency tools.

Description

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. This is used in `revdep_check` to avoid packages with installation problems or extremely long check times.
`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.

Examples

## Not run: 
revdep("ggplot2")

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

## End(Not run)
