\title{Use Fixed-Interval Smoothing on Time Series}
\description{
  Performs fixed-interval smoothing on a univariate time series via a
  state-space model.  Fixed-interval smoothing gives the best estimate
  of the state at each time point based on the whole observed series.
}
\usage{
tsSmooth(object, \dots)
}
\arguments{
  \item{object}{a time-series fit.  Currently only class
    \code{"\link{StructTS}"} is supported}
  \item{\dots}{possible arguments for future methods.}
}
\value{
  A time series, with as many dimensions as the state space and results
  at each time point of the original series.  (For seasonal models, only
  the current seasonal component is returned.)
