getHaltonFrame

internal

Encapsulates a number of spatially balanced sampling algorithms,
namely, Balanced Acceptance Sampling (equal, unequal, seed point, panels), Halton frames
(for discretizing a continuous resource), Halton Iterative Partitioning (equal probability)
and Simple Random Sampling.
