The copy hash method creates a independent copy of a hash object.  Creating
  a copy using the assingment operator, <code>&lt;-</code>, 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 <code>copy</code> method provides
  an identical unlinked copy of the hash.

copy-methods

This package implements a data structure similar to hashes
        in Perl and dictionaries in Python but with a purposefully R
        flavor. For objects of appreciable size, access using hashes
        outperforms native named lists and vectors.
