This is utils::sessionInfo()
re-written from scratch to both exclude
data that's rarely useful (e.g., the full collate string or base packages
loaded) and include stuff you'd like to know (e.g., where a package was
installed from).
session_info(pkgs = NULL, include_base = FALSE)
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.
Columns in the printed package list:
package
: package name
*
: whether the package is attached to the search path
version
: package version. If the version is marked with (!)
that
means that the loaded and the on-disk version of the package are
different.
date
: when the package was built, if this information is available.
This is the Date/Publication
or the Built
field from
DESCRIPTION
. (These are usually added automatically by R.)
Sometimes this data is not available, then it is NA
.
source
: where the package was built or installed from, if available.
Examples: CRAN (R 3.3.2)
, Github (r-lib/pkgbuild@8aab60b)
,
Bioconductor
, local
.
See package_info()
for the list of columns in the data frame that
is returned (as opposed to printed).
