Reverse morie_ts_difference()

Usage

morie_ts_undifference(dx, init = attr(dx, "init"), lag = attr(dx, "lag"))

Arguments

dx: A differenced series from morie_ts_difference() (carrying its init attribute), or a plain vector plus explicit init.
init: Optional list of leading values (defaults to the attribute).
lag: Optional lag (defaults to the attribute).

Value

The reconstructed numeric series.

Examples

x <- cumsum(1:10); dx <- morie_ts_difference(x)
all.equal(morie_ts_undifference(dx), x)
#> [1] TRUE
