setTime<- {hyd1d}

Set a WaterLevelDataFrame's slot time

Description

A function to set the slot time of an object of class WaterLevelDataFrame.

Usage

setTime(x) <- value

## S4 replacement method for signature 'WaterLevelDataFrame,POSIXct'
setTime(x) <- value

## S4 replacement method for signature 'WaterLevelDataFrame,POSIXlt'
setTime(x) <- value

## S4 replacement method for signature 'WaterLevelDataFrame,Date'
setTime(x) <- value

Arguments

x

an object of class WaterLevelDataFrame.

value

a new value of class c("POSIXct", "POSIXt") for the time slot. value has to have a length of one and has to be in the temporal range between 1960-01-01 00:00:00 CET and now (Sys.time() or NA.

Value

The function above sets a new value for the slot time and returns an object of class WaterLevelDataFrame. Since time is a slot relevant for the computation of the data.frame column w, w is set to NA and needs to be recomputed by functions like waterLevel or waterLevelPegelonline.
