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

(data.table::data.table()).
