R help - Nov 2012 - avarage my data each hour

Hello,

I have much more than one milion tempreture is gained each 15 seconds. So
each 15 seconds, I have one data.
How could I calculate avarage datas in each hour in R?

If you could help me.

Hello,

You should provide us with a data example. Since you haven't, look at 
the following code and see if you understand it.

# Make up some data
x <- Sys.time() + (1:1000)*15
y <- rnorm(1000)

brks <- cut(x, breaks = "hour")  # hour breaks
tapply(y, brks, mean)   # hourly means of 'y'


Hope this helps,
