How to Use R's get Function to Evaluate Strings as Variable Names in a Loop Index
Evaluating the Loop Index as a Variable Name, Rather Than a String In programming, variable names are used to identify and store values that can be accessed later in the code. However, sometimes it’s necessary to use the loop index or another variable name that happens to coincide with the variable we want to use. In this post, we’ll explore how to evaluate a string as the underlying value of a loop index, rather than just using it as a string.
