Using envDocument

The envDocument package provides a function env_doc() which collects information about the environment in which an analysis is run. Currently, this includes:

R version
Attached packages with version and repository
General system information including OS and user
Script information including working directory. script path and modification time
Git commit information for script including tracking status, commit status, and remote (if git2r is available)

The primary purpose is to capture information for inclusion in an analysis report. As such, the call to env_doc() should be made after all libraries are attached.

Some functions, especialy getScriptPath() (get path to calling script) and getRepo() (find git repo for calling script), may be useful in other settings.

Note: if the calling script is not tracked in a git repository then env_doc() or getRepo() will throw warnings. These can be disabled by setting git = FALSE (see examples).

Version 2.3.1 adds support for Domino Datalab environment reporting. To add this, set domino = TRUE in the call to env_doc().

Examples

library(envDocument) 
library(knitr)


env_doc() # with git2r installed

env_doc("table") # pretty-print output using knitr::kable

env_doc(git = FALSE) # without git2r or if script is not trakced.

env_doc(domino = TRUE) # optional - print information on Domino Datalab environment

The getScriptPath() function looks up the name of the script being run. If called in an interactive context it will return NA. get_scriptpath() is provided as an alias for backwards compatibility.
