R can save and reload the user's workspace between sessions via an .RData file in the current directory. However, long-term reproducibility is enhanced when you turn this feature off and clear R's memory at every restart. Starting with a blank slate provides timely feedback that encourages the development of scripts that are complete and self-contained. More detail can be found in the blog post Project-oriented workflow.

use_blank_slate(scope = c("user", "project"))



Edit globally for the current user, or locally for the current project


Only use_blank_slate("project") is automated so far, since RStudio currently only supports modification of user-level or global options via the user interface.
