Understanding R's Pass-By-Value Behavior and Returning Iteratively Updated Data Frames
Understanding R’s Pass-by-Value Behavior and Returning Iteratively Updated Data Frames Introduction R is a powerful programming language that offers various data structures, including the data.frame, to store and manipulate data. In this article, we’ll explore how to return an iteratively updated data.frame from a function in R. We’ll delve into the subtleties of pass-by-value behavior, scoping, and usage of the <- operator.
What is Pass-by-Value in R? In programming languages, including R, pass-by-value (PBV) means that when a function receives an argument, it does not modify the original variable but instead creates a copy of it.
