Create a vector of coefficients using an arbitrary function

Produces an object that may be used in place of a vector in the creation of arguments to spec_rescomp().

rescomp_coefs_vector_custom(func, length)

Arguments

func

A function that takes params (a list of parameters) and returns a vector.

length

The length of the vector returned by func.

Value

S3 object of class rescomp_coefs_vector.

Examples

# Vector with one time-varying coefficient
rescomp_coefs_vector_custom(
  function(params) {
    c(0.2, 0.3, 0.4, params$fourth_coeff)
  },
  length = 4
