Basics with sessionInfo

library(details)

One the most basic and popular uses for details is to paste the sessioninfo at the bottom of a GitHub issue.

Pro tip: When using details in knitr/rmarkdown documents there is no need to set the knitr chunk options to results=‘asis’, there are already predefined print methods for these environments.
