Kindly reply please  if any one can.
###
Hello R users,

I have a montly time series over a several year period.
It's easy to compute a monthly climatology (12 values), Now, I would like to
calculate the corresponding standard deviation, ie the 12 values
calculated from the january values, february values, etc.
What's the best way for such a calculation ?
Regards,
Yogesh

Actually, you did get a response from someone asking for more information about
what you were doing, and for some sample data so that the advice given would
actually be useful.  I presume everyone is waiting for the additional
information.

Most likely that's because you didn't clearly explain the problem.
Please read
the posting guide (see link at bottom of each and every message on this
list), and provide an example of your data, a clear description of what
you're trying to do, and what you have tried that hasn't worked.
