pac_deps: Package dependencies

Description

Package dependencies from DESCRIPTION files with installed or expected versions or newest released.

Usage

pac_deps(
  pac,
  fields = c("Depends", "Imports", "LinkingTo"),
  lib.loc = .libPaths(),
  base = FALSE,
  local = TRUE,
  description_v = FALSE,
  attr = TRUE,
  recursive = TRUE,
  repos = biocran_repos()
)

Value

data.frame with packages and their versions. Versions are taken from installed.packages or newest released.

Arguments

pac

character a package name.

fields

character vector listing the types of dependencies, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances"). Character string "all" is shorthand for that vector, character string "most" for the same vector without "Enhances", character string "strong" (default) for the first three elements of that vector. Default: c("Depends", "Imports", "LinkingTo")

lib.loc

character vector of search paths with local packages. Default: .libPaths()

base

logical if to add base packages too. If TRUE then pacs::pacs_base() are taken into account. Default: FALSE

local

logical if to use local repository (or newest remote packages). Default: TRUE

description_v

logical if the dependencies version should be taken from description files, minimal required. By default installed versions are taken. Default: FALSE

attr

logical if a package and its version should be added as an attribute of data.frame or for FALSE as an additional record. Default: TRUE

recursive

logical if to assess the dependencies recursively. Default: TRUE

repos

character vector of repositories URLs to use. By default checking CRAN and newest Bioconductor per R version. Default pacs::biocran_repos()

Examples

if (FALSE) {
pacs::pac_deps("stats", base = TRUE)$Package
pacs::pac_deps("memoise")$Package
pacs::pac_deps("memoise", description_v = FALSE)
# raw dependencies from DESCRIPTION file
pacs::pac_deps("memoise", description_v = TRUE, recursive = FALSE)
# raw dependencies from DESCRIPTION file - last release
pacs::pac_deps("memoise", description_v = TRUE, local = FALSE, recursive = FALSE)
