generate_design_lhs: Generate a Space-Filling LHS Design

In paradox: Define and Work with Parameter Spaces for Complex Algorithms

Generate a Space-Filling LHS Design

Description

Generate a space-filling design using Latin hypercube sampling. Dependent parameters whose constraints are unsatisfied generate NA entries in their respective columns.

Usage

generate_design_lhs(param_set, n, lhs_fun = NULL)

Arguments

param_set	(ParamSet).
n	(integer(1)) Number of points to sample.
lhs_fun	(function(n, k)) Function to use to generate a LHS sample, with n samples and k values per param. LHS functions are implemented in package lhs, default is to use lhs::maximinLHS().

Value

Design.

Examples

ps = ParamSet$new(list(
  ParamDbl$new("ratio", lower = 0, upper = 1),
  ParamFct$new("letters", levels = letters[1:3])
))

if (requireNamespace("lhs", quietly = TRUE)) {
  generate_design_lhs(ps, 10)
}
