Package dependencies — pac

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

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()
)

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()

Value

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

Note

When function is invoked in the loop afterwards results could be aggregated like, stats::aggregate(results[, c("Version"), drop = FALSE], list(Package = results$Package), pacs::compareVersionsMax).

Examples

if (FALSE) { # \dontrun{
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)
} # }
