Hi,

Thanks for the tip. I already had an .onLoad() function, with 

.onLoad <- function(lib,pkg) {
	require(methods)
        require(FLCore)
}

the first to comply with the needs of an S4 package, the second to solve
the internal dependency that outside of the bundle is solved with
Depends: in DESCRIPTION.

Is there anything else I could look at?

Thanks,


Iago
