Bind Two or More Time Series

Description:

     Bind time series which have a common frequency. 'ts.union' pads
     with 'NA's to the total time coverage, 'ts.intersect' restricts to
     the time covered by all the series.

Usage:

     ts.intersect(..., dframe = FALSE)
     ts.union(..., dframe = FALSE)

Arguments:

     ...: two or more univariate or multivariate time series, or
          objects which can coerced to time series.

  dframe: logical; if 'TRUE' return the result as a data frame.

Details:

     As a special case, '...' can contain vectors or matrices of the
     same length as the combined time series of the time series
     present, as well as those of a single row.

Value:

     A time series object if 'dframe' is 'FALSE', otherwise a data
     frame.

See Also:

     'cbind'.

Examples:

     ts.union(mdeaths, fdeaths)
     cbind(mdeaths, fdeaths) # same as the previous line
     ts.intersect(window(mdeaths, 1976), window(fdeaths, 1974, 1978))

     sales1 <- ts.union(BJsales, lead = BJsales.lead)
     ts.intersect(sales1, lead3 = lag(BJsales.lead, -3))
