Suppose you're writing a function in R to handle a complex set of conditions. How would you approach this to avoid deep nesting of if statements?

To avoid deep nesting of if statements when writing a function in R to handle complex conditions, you can employ various approaches. This includes breaking down the conditions into smaller functions or helper variables, utilizing functions like switch() or case_when() to handle multiple conditions concisely, and leveraging logical operators and vectorization for efficient conditional operations. These approaches help enhance code readability, maintainability, and performance.
