[R] Array as time series?

I have 4-dimensional atmospheric data (x,y,z,t), which I want to analyse
on spatio-temporal diversities.
As far as I understand there only exists the possibility to construct
time series as two-dimensional matrices (mts).
For the moment, I hold it in different objects:
1. a four-dimensional array for the spatial related analyses
2. a two-dimensional mts timeserie, which was derived from 1. by
computing spatial means.
But, still this doesn't help for combined spatio-temporal analysis.
One could regard the time dimension as just another linearily spaced
dimension in the four-dimensional array, but when it comes analyses and
graphics output it gets complicated, since one can't use all timeseries
(ts-) related functions (require ts attributes).
Could you provide me some comments, workarounds or your experiences on
Thanks in advance,
