pkgDep: Retrieves package dependencies.

In miniCRAN: Create a Mini Version of CRAN Containing Only Selected Packages

Retrieves package dependencies.

Description

Performs recursive retrieve for Depends, Imports and LinkLibrary. Performs non-recursive retrieve for Suggests.

Usage

pkgDep(
  pkg,
  availPkgs,
  repos = getOption("repos"),
  type = "source",
  depends = TRUE,
  suggests = TRUE,
  enhances = FALSE,
  includeBasePkgs = FALSE,
  Rversion = R.version,
  quiet = 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. "https://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().
depends	If TRUE, retrieves Depends, Imports and LinkingTo dependencies (non-recursively)
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
Rversion	Version of R (only used if type is not source.) Defaults to R.version, but this can be specified as any of the following formats: a character string with the two digit R version, e.g. "3.1" a list with components major and minor the result of getRversion() the result of R.version
quiet	If TRUE, suppresses warnings
...	Other arguments passed to available.packages()

Value

character vector of package names
