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.
