Get properties of filters

Usage

get_properties_function(
  x,
  component = c("Symmetric Gain", "Symmetric Phase", "Symmetric transfer",
    "Asymmetric Gain", "Asymmetric Phase", "Asymmetric transfer"),
  ...
)

Arguments

x: a "moving_average" or "finite_filters" object.
component: the component to extract.
...: unused other arguments.

Examples

filter <- lp_filter(3, kernel = "Henderson")
#> Error in .jcall("jdplus/filters/base/r/LocalPolynomialFilters", "Ljdplus/toolkit/base/core/math/linearfilters/ISymmetricFiltering;",     "filters", as.integer(horizon), as.integer(degree), kernel,     endpoints, d, tweight, passband): RcallMethod: cannot determine object class
sgain <- get_properties_function(filter, "Symmetric Gain")
#> Error in UseMethod("get_properties_function", x): no applicable method for 'get_properties_function' applied to an object of class "function"
plot(sgain, xlim= c(0, pi/12))
#> Error: object 'sgain' not found
