The emphasis in this case will probably be on clarity of user interface and documentation, which means style and code evaluation are important. Robustness and screening are essential in this sort of project too.
The difference between the hard-coded strategy as well as offer process is hanging. One is seven traces of difficult R code involving many subsetting levels and tiny, identical capabilities (e.
Building deals is good observe in terms of learning to correctly document your code, shop case in point info, and also (via vignettes) ensure reproducibility. But it really usually takes lots of extra time so shouldn't be taken frivolously. This approach to R workflow is suitable for running elaborate projects which continuously use the same routines which can be converted into functions.
