\arguments{
\item{x}{a time-series or other object.}
\item{start}{the start time of the period of interest.}
\item{end}{the end time of the period of interest.}
\item{warn}{if \code{FALSE} omit warnings about \code{start} and
    \code{end} being out of range.}
}
\description{
\code{window} is a generic function which
extracts the subset of the object \code{x}
observed between the times \code{start} and \code{end}.
Methods are available for time series and point-processes.
}
\note{The \code{warn} argument is for use by lazy \R programmers
    whose code requires \code{window} to do the checking silently.}
