paradox (version 0.3.0)

ParamInt: Integer Parameter

Description

A Param to describe integer parameters.

Methods

See Param.

Super class

paradox::Param -> ParamInt

Public fields

lower

(numeric(1)) Lower bound. Always NA for ParamFct, ParamLgl and ParamUty.

upper

(numeric(1)) Upper bound. Always NA for ParamFct, ParamLgl and ParamUty.

Active bindings

levels

(character() | NULL) Set of allowed levels. Always NULL for ParamDbl, ParamInt and ParamUty. Always c(TRUE, FALSE) for ParamLgl.

nlevels

(integer(1) | Inf) Number of categorical levels. Always Inf for ParamDbl and ParamUty. The number of integers in the range [lower, upper], or Inf if unbounded for ParamInt. Always 2 for ParamLgl.

is_bounded

(logical(1)) Are the bounds finite? Always TRUE for ParamFct and ParamLgl. Always FALSE for ParamUty.

storage_type

(character(1)) Data type when values of this parameter are stored in a data table or sampled. Always "numeric" for ParamDbl. Always "character" for ParamFct. Always "integer" for ParamInt. Always "logical" for ParamLgl. Always "list" for ParamUty.

Method new()

Creates a new instance of this R6 class.

Usage

ParamInt$new(
  id,
  lower = -Inf,
  upper = Inf,
  special_vals = list(),
  default = NO_DEF,
  tags = character()
)

Arguments

id

(character(1)) Identifier of the object.

lower

(numeric(1)) Lower bound, can be -Inf.

upper

(numeric(1)) Upper bound can be +Inf.

special_vals

(list()) Arbitrary special values this parameter is allowed to take, to make it feasible. This allows extending the domain of the parameter. Note that these values are only used in feasibility checks, neither in generating designs nor sampling.

default

(any) Default value. Can be from the domain of the parameter or an element of special_vals. Has value NO_DEF if no default exists. NULL can be a valid default.

tags

(character()) Arbitrary tags to group and subset parameters. Some tags serve a special purpose:

• "required" implies that the parameters has to be given when setting values in ParamSet.

Method clone()

The objects of this class are cloneable with this method.

Usage

ParamInt$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
