Manipulating Finite Filters

Usage

finite_filters(
  sfilter,
  rfilters = NULL,
  lfilters = NULL,
  first_to_last = FALSE
)

is.finite_filters(x)

# S4 method for class 'finite_filters'
show(object)

Arguments

sfilter: the symmetric filter (moving_average() object) or a matrix or list with all the coefficients.
rfilters: the right filters (used on the last points).
lfilters: the left filters (used on the first points).
first_to_last: boolean indicating if the first element of rfilters is the first asymmetric filter (when only one observation is missing) or the last one (real-time estimates).
x: object to test the class.
object: finite_filters object.
