# start

##### Encode the Terminal Times of Time Series

Extract and encode the times the first and last observations were taken. Provided only for compatibility with S version 2.

- Keywords
- ts

##### Usage

```
start(x, …)
end(x, …)
```

##### Arguments

- x
a univariate or multivariate time-series, or a vector or matrix.

- …
extra arguments for future methods.

##### Details

These are generic functions, which will use the
`tsp`

attribute of `x`

if it exists.
Their default methods decode the start time from the original time
units, so that for a monthly series `1995.5`

is represented
as `c(1995, 7)`

. For a series of frequency `f`

, time
`n+i/f`

is presented as `c(n, i+1)`

(even for `i = 0`

and `f = 1`

).

##### Warning

The representation used by `start`

and `end`

has no
meaning unless the frequency is supplied.
