[Bioc-devel] Importing generic functions from other pkgs and defining methods on them?

[Benilton Carvalho]

Sorry for not providing a reproducible example.

After a couple of days, I finally noticed that generic functions are  
not defined for ncol/nrow and that was what the problem for "image"  
to work for me (as I also define methods for both and naively assumed  
they were had generics).
