miniCRAN (version 0.2.12)

makeDepGraph: Create dependency graph from available packages.

Description

Each package is a node, and a dependency is an edge

Usage

makeDepGraph(pkg, availPkgs, repos = getOption("repos"),
  type = "source", suggests = TRUE, enhances = FALSE,
  includeBasePkgs = FALSE, ...)

Arguments

pkg

Character vector of packages.

availPkgs

Data frame with an element called package. The package element is a vector of available packages. Defaults to reading this list from CRAN, using available.packages()

repos

URL(s) of the 'contrib' sections of the repositories, e.g. "http://cran.us.r-project.org". Passed to available.packages()

type

Possible values are (currently) "source", "mac.binary" and "win.binary": the binary types can be listed and downloaded but not installed on other platforms. Passed to download.packages().

suggests

If TRUE, retrieves Suggests dependencies (non-recursively)

enhances

If TRUE, retrieves Enhances dependencies (non-recursively)

includeBasePkgs

If TRUE, include base R packages in results

...

Other arguments passed to available.packages()

See Also

pkgDep() to extract package dependencies

Other dependency functions: basePkgs, pkgDep, plot.pkgDepGraph
