abstract: 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.
