Extensible time series class for R built on zoo
What it is
An R package that provides uniform handling of R's different time-based data classes by extending zoo. It preserves information from the original formats as much as possible while letting users add their own attributes. R users working with financial time series in quantitative analysis are the intended audience. It is a data structure package rather than an analysis toolkit, and its benefits apply only within the R ecosystem.
