| mergeSeries {fame} | R Documentation |
Merge two time-indexed series using either the levels or the first differences of the second series where the series overlap.
mergeSeries(x, y, differences = F)
x, y |
tis objects, or objects that can sensibly be coerced to
tis by as.tis.
|
differences |
if T, the first differences of series are merged, and then
cumulatively summed. The default is F.
|
x and y must have the same tif (ti frequency),
and the same number of column (if they are multivariate).
A tis object series with start and end dates that span those of
x and y. Where the series overlap, values from y
are used.
