Combine univariate time series

Hallo everyone I have two univariate time series (class ts) describing the same variable. They have the same resolution, but span different periods in time with a big gap in between. I need to append one to the other such that they are one object, with the gap filled with NAs. The method ts.union produces a multivariate time series where the time axis is correct, but the individual time series are not combined into one.
If ts1 and ts2 are two ts series: both <- ts.union(ts1, ts2) pmax(both[,1], both[,2], na.rm = TRUE)
