Extract time series properties, such as the number of observations
(obs), the time differences between observations (obs), the number
of observations per year (freq), and the start time stamp (start)
and the end time stamp (end) of the series.
ts_summary(x, spark = FALSE)ts-boxable time series, an object of class ts, xts, zoo,
data.frame, data.table, tbl, tbl_ts, tbl_time, tis, irts or
timeSeries.
logical should an additional column with a spark-line added to the data frame (experimental, ASCII only on Windows.)
ts_summary returns a data.frame. Individual column can be
accessed through the $ notation (see examples).
