Array parameters

Create parameters that consist of multiple numbers. If an attempt is made to create a parameter with conflicting settings then an error will be thrown.

proportion_parameter_array(name, value, label)

binary_parameter_array(name, value, label)

integer_parameter_array(
  name,
  value,
  label,
  lower_limit = rep(as.integer(-.Machine$integer.max), length(value)),
  upper_limit = rep(as.integer(.Machine$integer.max), length(value))
)

numeric_parameter_array(
  name,
  value,
  label,
  lower_limit = rep(.Machine$double.xmin, length(value)),
  upper_limit = rep(.Machine$double.xmax, length(value))
)

Arguments

name

character name of parameter.

value

vector of values.

label

character vector of labels for each value.

lower_limit

vector of values denoting the minimum acceptable value for each element in value. Defaults to the smallest possible number on the system.

upper_limit

vector of values denoting the maximum acceptable value for each element in value. Defaults to the largest possible number on the system.

Value

ArrayParameter object.

Details

Below is a list of parameter generating functions and a brief description of each.

proportion_parameter_array

binary_parameter_array

a parameter that consists of multiple integer values that are either zero or one.

integer_parameter_array

a parameter that consists of multiple integer values.

numeric_parameter_array

a parameter that consists of multiple numeric values.
