S4 class implementation of irregularly spaced time seires.
The class implements Arith methods using date matching,
union, intersection, and other time series methods.
Objects from the Class
Objects can be created by calls of the form new("its", ...).
~~ describe objects here ~~
Slots
.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
Extends
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.
