sessioninfo

R Session Information

Lifecycle: stable R-CMD-check CRAN RStudio mirror downloads Codecov test coverage

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. GitHub repo and hash for packages installed from GitHub.
  • Highlight package installation problems, e.g. 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 if the reticulate package is loaded and configured.
  • Information about package libraries.
  • 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 the released version from CRAN

install.packages("sessioninfo")

Or the development version from GitHub:

# install.packages("pak")
pak::pak("r-lib/sessioninfo")

Usage

Example output:

sessioninfo::session_info()

Screenshot of a terminal window demonstrating example output of the sessioninfo function.

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")
