You treat xy.freekt as an S4 class and R thinks so too. The coef generic is S3. The default method for this generic extracts object$coefficients, and that can't work on an S4 class. This would explain the error you see: instead of using the appropriate method, the dispatching apparently uses the default S3 method. Can you link us to a github repo or so where we can see the code? I suspect either a problem with the NAMESPACE or with the class definitions. Are you sure freelsgen returns the class you expect it to return?
