90% of R tasks, especially providing print() , summary() , or plot() methods for new data types. Pros: Minimal boilerplate; easy to learn; highly flexible.

S3 is R’s original, informal OOP system. It is essentially a list with a "class" attribute. 90% of R tasks, especially providing print() ,

No formal validation; it relies on naming conventions (e.g., generic.class ). 2. S4: The Rigorous Contract It is essentially a list with a "class" attribute

Strict type checking; multiple dispatch (methods can choose logic based on multiple arguments). Cons: High "ceremony" and steep learning curve. 3. R6: The Modern Powerhouse

The first step in strategic selection is understanding the fundamental divide in R’s approach to objects:

Requires an external dependency; can lead to "non-idiomatic" R code if overused. 4. Reference Classes (RC): The Internal Alternative
