In ParamHelpers: Helpers for Parameters in Black-Box Optimization, Tuning and Machine Learning

Return lengths of single parameters or parameters in parameter set.

Description

Useful for vector parameters.

Usage

getParamLengths(par, dict = NULL)

Arguments

par	(Param | ParamSet) Parameter or parameter set.
dict	(environment | list | NULL) Environment or list which will be used for evaluating the variables of expressions within a parameter, parameter set or list of parameters. The default is NULL.

Value

(integer). Named and in the same order as the input for ParamSet() input.

Examples

ps = makeParamSet(
  makeNumericParam("u"),
  makeIntegerParam("v", lower = 1, upper = 2),
  makeDiscreteParam("w", values = 1:2),
  makeDiscreteVectorParam("x", len = 2, values = c("a", "b"))
)
getParamLengths(ps)
# the length of the vector x is 2, for all other single value parameters the length is 1.

par = makeNumericVectorParam("x", len = expression(k), lower = 0)
getParamLengths(par, dict = list(k = 4))
