  We exhibit an infinite family of vector-valued mock theta functions indexed
by positive integers coprime to $6$. These are built from specializations of
Dyson's rank generating function and related functions studied by Watson,
Gordon, and McIntosh. The associated completed harmonic Maass forms transform
according to the Weil representation attached to a rank one lattice. This
strengthens a 2010 result of Bringmann and Ono and a 2019 result of Garvan.
