⚠️There's a newer version (1.8-14) of this package.Take me there.

zoo (version 1.8-4)

S3 Infrastructure for Regular and Irregular Time Series (Z's Ordered Observations)

Description

An S3 class with methods for totally ordered indexed observations. It is particularly aimed at irregular time series of numeric vectors/matrices and factors. zoo's key design goals are independence of a particular index/date/time class and consistency with ts and base R by providing methods to extend standard generics.
