You need to look at your NAMESPACE file, not the DESCRIPTION file.  It's 
likely that Roxygen has included both imports of combine in that file, 
and that *is* a problem:  only one will be valid.  (You can't have two 
objects with the same name, but you can import one of them using a 
different name.)

If you can't spot the problem, please post either the NAMESPACE file, or 
even better, a location of the whole package so we can take a look.
