Various standard methods for <code>zoo</code> time series
that are fully exported and documented for historical reasons.

zoo-methods

An S3 class with methods for working with regular and irregular time series.
The class stores data as numeric vectors/matrices (or factors) along with a time index of arbitrary class
(including numeric, Date, POSIXct, chron, yearmon, yearqtr, etc.). Functions and methods
are consistent with the ts class and base R and also extend standard generics. Tools include:
Data import/export, coercion, visualization (with base R, 'ggplot2', 'lattice', 'tinyplot'), alignment and merging,
aggregation, lags and subsets, rolling analytics, and time-based interpolation/filling.
The design is introduced in Zeileis and Grothendieck (2005) <doi:10.18637/jss.v014.i06>.
