[R] time series-V+R

[Ben Bolker]

  Have you looked at the online R complements?
  Although R and S-PLUS have similar functionality, this is one place
where the cosmetic details are somewhat different.
  As it turns out, the logarithmic confidence intervals are constant for
spectra, so they *are* the same for all frequencies.  (I don't know how
much detail V&R provide, since my copy is 5000 miles away, but I'm sure
they at least give references.)
