Generate a Space-Filling Sobol Sequence Design

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

Uses spacefillr::generate_sobol_set.

Note that non determinism is achieved by sampling the seed argument via sample(.Machine$integer.max, size = 1L).

Usage

generate_design_sobol(param_set, n)

Arguments

param_set

(ParamSet).

n

(integer(1))
Number of points to sample.

Value

Design.

Examples

pset = ps(
  ratio = p_dbl(lower = 0, upper = 1),
  letters = p_fct(levels = letters[1:3])
)

if (requireNamespace("spacefillr", quietly = TRUE)) {
  generate_design_sobol(pset, 10)
}
