ts_regular: Enforce Regularity

In tsbox: Class-Agnostic Time Series

Description

Enforces regularity in data frame and xts objects, by turning implicit NAs into explicit NAs. In ts objects, regularity is automatically enforced.

Usage

ts_regular(x, fill = NA)

Arguments

x	ts-boxable time series, an object of class ts, xts, zoo, data.frame, data.table, tbl, tbl_ts, tbl_time, tis, irts or timeSeries.
fill	instead of NA, an alternative value can be specified

Examples

x0 <- AirPassengers
x0[c(10, 15)] <- NA
x <- ts_na_omit(ts_dts(x0))
ts_regular(x)
ts_regular(x, fill = 0)

m <- mdeaths
m[c(10, 69)] <- NA
f <- fdeaths
f[c(1, 3, 15)] <- NA

ts_regular(ts_na_omit(ts_dts(ts_c(f, m))))
