Making R-Package: NAMESPACE

I am creating a R-package and I am at the step where I BUILD the package.

I have read the Writing R Extensions documentation about NAMESPACE (more specifically the sections 1.5.1 and 1.5.2 on import, export and on registering S3method).

I am worrying about this step because when I CHECKmy package I got this warning:

Found the following apparent S3 methods exported but not registered: print.myClass print.myOtherClass summary.myClass summary.myOtherClass See section 'Registering S3 methods' in the 'Writing R Extensions' manual.

Any help in deciphering what are the consequences of not registering a S3method and about the NAMESPACE file in general would make my day.

Thanks for your help.

I would bet 10:1 that you wrote something like 

export(print.myClass)

in the namespace. Instead, you need to write

S3method(print, myClass)
