[R-SIG-Finance] Timeseries data, lattice, and model formulas?

Hello All,

I'm using R for a rather large, multivariate timeseries dataset of ~4
million records.  So far I've divided the set and used conventional
data frames with good success at visualizing, summary statistics, etc.

I've experimented with dedicated timeseries packages like its and zoo
for more complicated analysis, but support for things like factors,
lattice and model formulas seems lacking.  Am I missing something, or
are data frames the most appropriate vehicle for large, multivariate

thanks so much

Far better an approximate answer to the right question, which is often
vague, than the exact answer to the wrong question, which can always
be made precise -- j.w. tukey
