R help - May 2007 - time series

Dear all,

I am working with a data file which is the record of precipitation
measurement normaly done every 10 minutes. I would like to check if there
are missing times in my data file.

Is there a function existing able to check for that in R ?

Thanks by advance,


Jessica

I'd use max(diff(time))==min(diff(time)).

HTH,

Can you give us a little more information?  Are you
expecting N times to be record and want to know if you
only have N-x times or are you expecting N entries but
want to know if some are NA?  Etc, etc...

Also are you actually recording the times or is the
sampling setup just taking a sample every 10 minutes,
that is, you can assume that every sample is at a ten
minute interval because of the equipment set-up?
