Linear Filtering on a Time Series
Applies linear filtering to a univariate tis series or to each
column separately of a multivariate tis series.
tisFilter(x, ...)
x |
a univariate or multivariate time series. |
... |
arguments passed along to |
A tis time indexed series with leading and trailing
NA values stripped.
If ever the filter() function is made generic, as it should be,
this function could become the tis method for it.
x <- tis(1:100, start = c(2000,1), freq = 12) tisFilter(x, rep(1, 3)) tisFilter(x, rep(1, 3), sides = 1) tisFilter(x, rep(1, 3), sides = 1, circular = TRUE)
