copy-methods: Create a seperate copy of a hash object.
Description
The copy hash method creates a independent copy of a hash object. Creating
a copy using the assingment operator, <-, does not work as expected,
since hashes are based on environments and environments are reference objects
in R. The assignment operator consequently creates a linked copy to the
original hash and not an independent copy. The copy method provides
an identical unlinked copy of the hash.
Arguments
Value
A hash object.
Methods
signature(x = "hash")
Creates and returns an identical, independent, unreferenced copy of the
the hash.
