[R] Help with the ts function

I have a time series of temperature data recorded every 2 hours and I would like to generate a spectrogram using the spectrum function that examines cycles per day. My statement for coding the series using the ts function is


where 0.0833334 is 2 hours/24 hours.

I am wondering if this is the correct way to code the data?

Thanks for your help.

Gary Nelson.
