[Rd] How to get the names of the classes exported by a specific package.

[ernesto]

Hi,

I'm writing some functions to generate Rd files for a S4 package. I want 
to have 2 character vectors with the names of the S4 classes and the 
methods exported by a package. To get the info about methods I'm using 
"getGenerics(where="package:FLCore")" however I can not find a similar 
process to get the S4 classes. Are there functions to access this 
information ?

Best and thanks
