package_info

From sessioninfo v1.1.1 by Gabor Csardi

package_info(pkgs = NULL, include_base = FALSE, dependencies = NA)

pkgs: Either a vector of package names or NULL. If NULL, displays all loaded packages. If a character vector, also, includes all dependencies of the package.
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().

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.
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).
