# quaternion: Quaternions using Clifford algebras In clifford: Arbitrary Dimensional Clifford Algebras

## Description

Converting quaternions to and from Clifford objects is not part of the package but functionality and a short discussion is included in inst/quaternion_clifford.Rmd.

## Details

Given a quaternion \mjeqna+bi+cj+dka+bi+cj+dk, one may identify \mjeqnii with \mjeqn-e_12-e_12, \mjeqnjj with \mjeqn-e_13-e_13, and \mjeqnkk with \mjeqn-e_23-e_23 (the constant term is of course \mjeqne_0e_0).

## Note

A different mapping, from the quaternions to \mjseqnCl(0,2) is given at signature.Rd.
