Time Windows

Description

window is a generic function which extracts the subset of the object x observed between the times start and end. Methods are available for time series and point-processes.

Usage

window(x, start=NULL, end=NULL, warn=TRUE)

Arguments

x a time-series or other object.
start the start time of the period of interest.
end the end time of the period of interest.
warn if FALSE omit warnings about start and end being out of range.

Note

The warn argument is for use by lazy R programmers whose code requires window to do the checking silently.

sixties <- window(presidents, 1960, c(1969,4))
