R is used in a vast ways. From pure ad-hoc by hobbysts to an organized and structured way in an enterprise. Each way of R usage brings different reproducibility challenges. Going through range of typical workflows we will show that understanding reproducibility must start with understanding your workflow. Presenting workflows we will show how we deal reproducibiilty challenges with open-source R Suite (http://rsuite.io) solution developed by us to support our large scale R development.

Reproducibility is the
ability to run your code repeatedly,
at different time,
using different computer,
in such way to
obtain the same outputs given the
same inputs.
