%description
A comprehensive implementation of dynamic time warping (DTW) algorithms in
R.  DTW computes the optimal (least cumulative distance) alignment between
points of two time series.  Common DTW variants covered include local
(slope) and global (window) constraints, subsequence matches, arbitrary
distance definitions, normalizations, minimum variance matching, and so
on.  Provides cumulative distances, alignments, specialized plot styles,
etc., as described in Giorgino (2009) <doi:10.18637/jss.v031.i07>.
