Why your S3 method isn’t working

This technical article addresses a common debugging issue in R programming: custom S3 methods that fail while built-in methods like print() work. It explains that the error often occurs because a generic function (e.g., count_letters()) wasn't defined before creating the method (count_letters.myS3). The post includes code examples to demonstrate the problem and its solution, focusing on the S3 dispatch system.
