This is cbind for tis objects. It binds several
ts and tis objects together into a single matrix time
indexed series.
# S3 method for tis
cbind(…, union = F)any number of univariate or multivariate ts or tis
objects. All will be converted to tis objects by
as.tis, and the result series all must have the same
tif (time index frequency).
a logical. If union = F, a matrix created by the
intersection of the time windows for the arguments will be created.
If union = T, the union of the time windows will be used to
create the matrix.
a multivariate tis object.
If union is TRUE and the series in … do not all
start and end on the same time index, the missing observations are
filled with NA.
The column names of the returned series are determined as follows:
If an argument was given a name in the call, the corresponding column has that name. If the argument was itself a matrix with column names, those will be used, otherwise the argument's name is expanded with digits denoting its respective columns.
