Building deals is sweet observe when it comes to Discovering to correctly document your code, keep case in point knowledge, and perhaps (by way of vignettes) be certain reproducibility. But it surely usually takes a lot of extra time so shouldn't be taken lightly. This method of R workflow is appropriate for taking care of elaborate projects which repeatedly use the same routines which may be transformed into capabilities.
