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.
