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()
)

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

## Not run: 
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)

## End(Not run)
