Q: A prior data analyst used R to develop a set of nested functions that perform various actions on a set of data. The analyst’s goal is to do the same tasks while simplifying the code so that its stakeholders can comprehend it. Which one of these tools can the analyst utilize to make this happen?
- Pipe
- Comment
- Argument
- Vector
Explanation: The data analyst may utilize R’s pipe operator (%>%) to simplify nested function calls and make the code more easily understandable for the people who have a stake in the project. In most cases, the magrittr or dplyr packages are the ones that are linked with the pipe operator.
The analyst is given the flexibility to chain actions in a left-to-right sequence when they make use of the pipe operator, which improves readability and reduces the necessity for nested function calls. Workflows involving data modification and analysis benefit tremendously from its use.
