[R] ts or xts with high-frequency data within a year

I have a time series that represents data sampled every 15-minutes. The
data currently run from November through February, 8623 total readings.
There are definitely daily periodic trends and non-stationary long-term
trends. I would love to decompose this using basic time series analysis.
However, every time I attempt decomposition, I get the
Error in decompose( ) : time series has no or less than 2 periods
Is it only possible to do basic time-series analysis if you have a year or
more worth of data? That seems absurd to me, since there is definite
periodicity and the data are a time series. I have tried every manner of
specifying frequency= with no luck (96 does not work). All manner of
searching for help has turned up fruitless.
Can I only do this after I wait another year or two?
