(synopsis "Interpolate data for smooth animations")
(description
"In order to create smooth animation between states of data, tweening is
necessary. This package provides a range of functions for creating tweened
data that can be used as basis for animation. Furthermore it adds a number of
vectorized interpolaters for common R data types such as numeric, date and
color.")
