R Session Information

Lifecycle: stable R build status CRAN RStudio mirror downloads Coverage Status

Query and print information about the current R session. It is similar to utils::sessionInfo(), but includes more information about packages, and where they were installed from.

Differences from utils::sessionInfo()

  • Additional platform details: time zone, pandoc version, RStudio version, etc.
  • Information about package sources, e.g.Β GitHub repo and hash for packages installed from GitHub.
  • Highlight package installation problems, e.g.Β if the loaded and on-disk versions are different, if the MD5 checksum of the package DLL is wrong, etc.
  • Highlight packages from unusual sources.
  • Information about external software via external_info().
  • Information about the Python configuration is the reticulate package is loaded and configured.
  • Information about package libraries.
  • Emoji hash to be able to quickly tell if two sessions are equivalent.
  • Compare two session info outputs with the session_diff() function.
  • Option to show loaded (default), attached or installed packages, or the recursive dependencies of the specified packages.

Installation

install.packages("sessioninfo")

Usage

Example output:

sessioninfo::session_info()

Copying to the clipboard

You can use the clipr package to copy the session info to the clipboard:

clipr::write_clip(session_info())

(The current clipr version prints a warning, but you can ignore that.)

Writing to a file

You can use the to_file argument of session_info():

session_info(to_file = "session.log")

External software

sessioninfo::session_info(info = "external")

Comparing session information

session_diff() can retrieve the session info from an URL or the clipboard and compare it to the current session information:

sessioninfo::session_diff(new = "https://github.com/r-lib/sessioninfo/issues/6")
