In data frame objects (data.frame, tibble, data.table), tsbox
automatically detects the time and the value column. This function changes
the column names to the defaults (time, value), so that auto-detection
can be avoided in future operations.
Arguments
- x
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 x, i.e., an object of
class ts, xts, zoo, zooreg, data.frame, data.table, tbl,
tbl_ts, tbl_time, tis, irts or timeSeries.
Examples
# \donttest{
df <- ts_df(ts_c(mdeaths, fdeaths))
# non-default colnames
colnames(df) <- c("id", "date", "count")
# switch back to default colnames
ts_default(df)
