window {base} | R Documentation |
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.
window(x, start=NULL, end=NULL, warn=TRUE)
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. |
The warn
argument is for use by lazy R programmers
whose code requires window
to do the checking silently.
