Hi
I have a time series of measurements: every 10 min. a value was logged.
The data look like:
20100914 08:01 3.74
20100914 08:11 3.74
20100914 08:21 3.71
20100914 08:31 4.39
20100914 08:41 3.74
This data spans several months.
I would like to group the data per day. In

)
dat
split(dat$V3, dat$V1)
This gives you a list where each element is a (1-dimensional) vector,
and each of those
