build_tsibble_meta() does much less checks than build_tsibble() for
high performance.
build_tsibble_meta(
x,
key_data = NULL,
index,
index2,
ordered = NULL,
interval = NULL
)A data.frame, tbl_df, tbl_ts, or other tabular objects.
A data frame containing key variables and .rows. When a data
frame is supplied, the argument key will be ignored.
Quoted variable name.
TRUE suggests to skip the ordering as x in
the correct order. FALSE checks the ordering and may give a warning.
TRUE automatically calculates the interval, and FALSE for
irregular interval. Use the specified interval via new_interval() as is.
