S4 class implementation of irregularly spaced time seires. The class implements Arith methods using date matching, union, intersection, and other time series methods.

Objects can be created by calls of the form `new("its", ...)`

.

`.Data`

:Object of class

`"matrix"`

the data portion of the time series`dates`

:Object of class

`"POSIXt"`

the date vector portion of the time series

Class `"matrix"`

, from data part.
Class `"structure"`

, by class "matrix", distance 2.
Class `"array"`

, by class "matrix", distance 2.
Class `"vector"`

, by class "matrix", distance 3, with explicit coerce.
Class `"vector"`

, by class "matrix", distance 4, with explicit coerce.
