lib_status {pkgdepends}

Status of packages in a library

Description

Query data of all packages in a package library.

Usage

lib_status(library = .libPaths()[1], packages = NULL)

Arguments

library

Path to library.

packages

If not NULL, then only these packages are shown.

Value

Data frame that contains data about the packages installed in the library.

It has always has columns:

• biocviews: the corresponding field from DESCRIPTION, it must be present for all Bioconductor packages, other packages typically don't have it.

• built: the Built field from DESCRIPTION.

• depends, suggests, Imports, linkingto, enhances: the corresponding fields from the DESCRIPTION files.

• deps: A list or data frames, the dependencies of the package. It has columns: ref, type (dependency type in lowercase), package (dependent package, or R), op and version, for last two are for version requirement. op can be >=, >, == or <=, although the only the first one is common in practice.

• library: path to the package library containing the package.

• license: from DESCRIPTION.

• md5sum: from DESCTIPTION, typically NA, except on Windows.

• needscompilation: from DESCRIPTION, this column is logical.

• package: package name.

• platform: from the Built field in DESCRIPTION, the current platform if missing from DESCRIPTION.

• priority: from DESCRIPTION, usually base, recommended, or missing.

• ref: the corresponding ⁠installed::*⁠ package reference.

• repository: from DESCRIPTION. For packages from a CRAN repository this is CRAN, some other repositories, e.g. R-universe adds the repository URL here.

• repotype: cran, bioc or missing.

• rversion: from the Built field. If no such field, then the current R version.

• sysreqs: the SystemRequirements field from DESCRIPTION.

• title: package title.

• type: always installed.

• version: package version (as string).

Most of these columns are unchanged from DESCRIPTION, but pkgdepends also adds a couple.

Notes:

• In addition, it also has all ⁠remote*⁠ and ⁠config/needs/*⁠ entries from the DESCRIPTION files. (Case insensitive.)

• All columns are of type character, except for needscompilation, which is logical and deps, which is a list columns.

• If an entry is missing for a package, it is set to NA.

• Note that column names are lowercase, even if the corresponding entries are not in DESCRIPTION.

• The order of the columns is not deterministic, so don't assume any order.

• Additional columns might be present, these are internal for pkgdepends and should not be used in user code.
