Hello list,
I am writing a package which builds on a function ("foo") of another
package. I only need that particular function. What is the state of
the art to do this? Do I need a NAMESPACE file in my package?
Currently I still don't have one. Or can I do this with the Imports
field in my DESCRIPTION file? Reading chapter 1 of the "Writing R
Extensions" manual I do not completely understand for what situations
these two alternatives are intended for. The manual says that with
the Imports field of DESCRIPTION I can "import the name space" of
another package. What does that mean? What are the differences
between the two alternatives? Are there consequences for how I can
access function "foo" within the code of my package?
Thanks for some clarifications and recommendations!
Wolfgang Koller
