A start date of a format compatible with the time series
end.
warn
A logical indicating if warning should be produced
Value
A time series object similar to x, but typically spanning a shorter time period.
Details
This function calls window but makes more effort to preserve series.names
if the x has them. It also supports the optional
argument warn to suppress
warning messages. Frequently it is convenient to write code which always
truncates to a window without first checking if the data is already within
the window. Since window produces a warning in this situation, the optional
argument is frequently useful when tfwindow is used by other code.
