Did you mean:

average environmental data if AnimalID and Time is duplicated
...quot;27","28")
)
myframe
As you can see for Ernie I do have different data for 24.09.2012 9:00. Now I
would like to average the Hunger and Temp value for this timestamp to get a
data frame without duplicated Times and the respective average Temp and
Hunger.
I tried something like
Meanframe<- by(myframe[, 3:4], duplicated(myframe$ID,
Zusatzdaten3$Timestamp) == TRUE, mean)
but it doesn't work and I guess that it is also totally crap ;-)
