Imagine you need to refactor a piece of R code for better efficiency. How would you approach it?
- Identify bottlenecks, Use efficient data structures, Vectorize operations
- Ignore inefficiencies and hope the script runs faster
- None of the above
- Rewrite the entire script
Refactoring R code for efficiency involves identifying bottlenecks in the code (using profilers like Rprof), using more efficient data structures (like data.table), and vectorizing operations where possible. This approach can lead to significant performance improvements.
