Information about the currently loaded packages, or about a chosen set
package_info(pkgs = NULL, include_base = FALSE, dependencies = NA)
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 packages in summary? By default this is false since base packages should always match the R version.
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
.
