[R-pkg-devel] double colon

[Berry Boessenkool]

Hi,
in our Berlin R User Group meeting yesterday we talked about dependencies in package development.
One thing that came up is that it's a good practice to explicitly write   package::function   in the code.

Is it worth to go through all of my package and enhance the code in all instances? 
Or do you think that NAMESPACE sufficiently prevents using a function with the same name from another package than intended and people reading source code should be aware of that anyways?
If Answer1==YES:
Should I also refer to other functions within my own package through   myPackage::otherFunction?
Should I do that for base packages like graphics, stats, utils, grDevices? (we have to declare them in the NAMESPACE imports, after all)
What's a fast and easy way to find all the instances of 'external' function usage?

I guess there must be discussions and guidelines about this, so some pointers instead of answers would be fine as well.
Thanks ahead,
Berry
