[R] How to threshold point in time series

Hi All, I am having very high-frequency data, captured between 3 to 7 seconds by sensor for liquid tank and capacity of tank is 50k dm3. When tank capacity reduce to 1k dm3, than tank refilling need to call. How in time series we can perform, refilling can call when tank capacity reduce to 1k dm3,

[R] How to predict time series high-frequency data?

and which kinds of algorithm required to solve this problem using R. Thanks, Rama Shankar [[alternative HTML version deleted]] __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PL
