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,
Rui Barradas
