graph: Generate a Package Dependency Graph

Description

Generate a package dependency graph.

Usage

graph(
  root = NULL,
  leaf = NULL,
  ...,
  suggests = FALSE,
  enhances = FALSE,
  resolver = NULL,
  renderer = c("DiagrammeR", "visNetwork"),
  attributes = list(),
  project = NULL
)

Arguments

root

The top-most package dependencies of interest in the dependency graph.

leaf

The bottom-most package dependencies of interest in the dependency graph.

...

Unused arguments, reserved for future expansion. If any arguments are matched to ..., renv will signal an error.

suggests

Should suggested packages be included within the dependency graph?

enhances

Should enhanced packages be included within the dependency graph?

resolver

An R function accepting a package name, and returning the contents of its DESCRIPTION file (as an R data.frame or list). When NULL (the default), an internal resolver is used.

renderer

Which package should be used to render the resulting graph?

attributes

An R list of graphViz attributes, mapping node names to attribute key-value pairs. For example, to ask graphViz to prefer orienting the graph from left to right, you can use list(graph = c(rankdir = "LR")). See https://graphviz.org/doc/info/attrs.html for a full list of the attributes supported by graphViz.

project

The project directory. If NULL, then the active project will be used. If no project is currently active, then the current working directory is used instead.

Examples

# NOT RUN {
# }
# NOT RUN {
# graph the relationship between devtools and rlang
graph(root = "devtools", leaf = "rlang")

# figure out why a project depends on 'askpass'
graph(leaf = "askpass")
# }
# NOT RUN {
# }
