[R] Class definition and "contains": No definition was found for superclass

[Johannes Graumann]

Hi,

What goes wrong when the following error shows up:
> Error in reconcilePropertiesAndPrototype(name, slots, prototype,
> superClasses,  : 
>   No definition was found for superclass “sequencesuperclass” in the
>   specification of class “sequences”

Has this something to do with recursive class inheritance? "sequences" 
contains "sequencessuperclass" contains "rcfpdsuperclass" ...

Any hint is highly appreciated.

Sincerely, Joh
