Concatenates the tail of the previous time series (`prev`) with the current one (`curr`),
keeping only the last `n_former` points from `prev`. If `prev` is `NA`, returns `curr` unchanged.
Usage
concat_ts(prev = NA, curr, n_former)
Arguments
- prev
A `ts` object or `NA` (default). Previous time series.
- curr
A `ts` object. Current time series.
- n_former
An integer. Number of tail points from `prev` to keep.
Value
A new concatenated `ts` object.
Examples
if (FALSE) { # \dontrun{
prev <- ts(1:100, start = 0, frequency = 1)
curr <- ts(101:105, start = 100, frequency = 1)
concat_ts(prev, curr, n_former = 5)
} # }
