its (version 1.1.8)

its-class: Class "its" Irregularly Spaced Time-Series

Description

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

Arguments

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.
