start {stats} R Documentation
Encode the Terminal Times of Time Series
Description
Extract and encode the times the first and last observations were taken. Provided only for compatibility with S version 2.
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.
