How can S3 generic/method consistency be maintained when requiring different arguments?

edit

S3 generic/method consistency can be maintained by defining separate function/method names for different argument combinations. For example, if a generic function has two arguments A and B, and a method is defined for both arguments, (i.e., method(A,B)), then a separate function name can be defined for when only A is required (i.e., method(A)) and when only B is required (i.e., method(B)). This allows the user to call the appropriate function based on the argument inputs and ensures consistency in the naming convention of the functions/methods.

Alternatively, if there is a need to have a consistent function name for varying argument combinations, then it is important to document the expected arguments for each method and their order. This helps to avoid confusion and ensures that the user provides the correct input parameters. Additionally, proper error handling can be implemented to notify the user if the wrong argument combination is provided.
