package_info {sessioninfo}

Information about the currently loaded packages, or about a chosen set

Description

Information about the currently loaded packages, or about a chosen set

Usage

package_info(
  pkgs = c("loaded", "attached", "installed")[1],
  include_base = FALSE,
  dependencies = NA
)

Arguments

pkgs

Which packages to show. It may be:

• NULL or "loaded": show all loaded packages,

• "attached": show all attached packages,

• "installed": show all installed packages,

• a character vector of package names. Their (hard) dependencies are also shown by default, see the dependencies argument.

include_base

Include base packages in summary? By default this is false since base packages should always match the R version.

dependencies

Whether to include the (recursive) dependencies as well. See the dependencies argument of utils::install.packages().

Value

A data frame with columns:

• package: package name.

• ondiskversion: package version (on the disk, which is sometimes not the same as the loaded version).

• loadedversion: package version. This is the version of the loaded namespace if pkgs is NULL, and it is the version of the package on disk otherwise. The two of them are almost always the same, though.

• path: path to the package on disk.

• loadedpath: the path the package was originally loaded from.

• attached: logical, whether the package is attached to the search path.

• is_base: logical, whether the package is a base package.

• date: the date the package was installed or built, in UTC.

• source: where the package was installed from. E.g. CRAN, GitHub, local (from the local machine), etc.

• md5ok: Whether MD5 hashes for package DLL files match, on Windows. NA on other platforms.

• library: factor, which package library the package was loaded from. For loaded packages, this is (the factor representation of) loadedpath, for others path.

See session_info() for the description of the printed columns by package_info (as opposed to the returned columns).
