setTime<- {hyd1d} | R Documentation |
A function to set the slot time
of an object of class
WaterLevelDataFrame.

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

setTime(x) <- value
x |
an object of class WaterLevelDataFrame. |
value |
a new value of class |
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
.
wldf <- WaterLevelDataFrame(river = "Elbe",
time = as.POSIXct("2016-12-21"),
station = seq(257, 262, 0.1))
setTime(wldf) <- as.POSIXct("2016-12-22")
