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 = c("loaded", "attached", "installed")[1],
include_base = FALSE,
info = c("auto", "all", "platform", "packages", "python", "external"),
dependencies = NA,
to_file = FALSE
)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 packages in summary? By default this is false since base packages should always match the R version.
What information to show, it can be "auto" to choose
automatically, "all" to show everything, or a character vector
with elements from:
"platform": show platform information via platform_info(),
"packages": show package information via package_info(),
"python": show Python configuration via python_info(),
"external": show information about external software, via
external_info().
Whether to include the (recursive) dependencies
as well. See the dependencies argument of utils::install.packages().
Whether to print the session information to a file.
If TRUE the name of the file will be session-info.txt, but
to_file may also be a string to specify the file name.
A session_info object.
If to_file is not FALSE then it is
returned invisibly. (To print it to both a file and to the screen,
use (session_info(to_file = TRUE)).)
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).
