Enforces regularity in data frame and xts objects, by turning implicit
NAs into explicit NAs. In ts objects, regularity is automatically
enforced.
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
x0 <- AirPassengers
x0[c(10, 15)] <- NA
x <- ts_na_omit(ts_dts(x0))
ts_regular(x)
