get_all_reverse_dependencies

Get all reverse dependencies

get_all_reverse_dependencies(packages, level = 1L, relation = c("Depends",
  "Imports", "LinkingTo", "Suggests", "Enhances"), strict = FALSE,
  ignore = c("datasets", "utils", "grDevices", "graphics", "stats",
  "methods"))

Arguments

packages	(non-empty character vector) Package names
level	(positive integer, Default = 1L) Depth of recursive dependency
relation	(character vector) Types of relations. Must be a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances")
strict	(logical, Default: TRUE) Whether to consider all packages (alternately only 'relation' specific packages) when computing dependencies for the next level
ignore	package names to ignore

Value

A tibble with three columns: `pkg_1`, `relation` and `pkg_2`
