Combine time series to a new, single time series. ts_bind combines time
series as they are, ts_chain chains them together, using percentage change
rates.
Arguments
- ...
ts-boxable time series, an object of class
ts,xts,zoo,zooreg,data.frame,data.table,tbl,tbl_ts,tbl_time,tis,irtsortimeSeries.
Value
a ts-boxable object of the same class as the input, i.e., an object
of class ts, xts, zoo, zooreg, data.frame, data.table, tbl,
tbl_ts, tbl_time, tis, irts or timeSeries.
If series of different classes are combined, the class of the first series
is used (if possible).
Details
In data frame objects, multiple time series are stored in a long data frame.
In ts and xts objects, time series are combined horizontally.
