zip-methods: Convert between parallel vectors and lists

Description Usage Arguments Value See Also Examples

Description

The zipup and zipdown functions convert between two parallel vectors and a list of doublets (elements of length 2). The metaphor, borrowed from Python's zip, is that of a zipper. The zipup function interleaves the elements of the parallel vectors into a list of doublets. The inverse operation is zipdown, which returns a Pairs object.

Usage

For zipup, any vector-like object. For zipdown, a doublet list.
