Generate the replicates of a scenario, reusing them across methods

Equivalent to target_data$generate(n_replicates), with the same result and the same random number generator state afterwards. When cache_dir is given and generation is slow enough to be worth storing, the replicates are written there, and a later call with the same target data, replicate count and generator state reads them back instead.

Usage

generate_replicates(
  target_data,
  n_replicates,
  cache_dir = NULL,
  min_seconds = 0.25
)

Arguments

target_data

Target data object.

n_replicates

Number of replicates.

cache_dir

Directory to store replicates in, or NULL to generate them every time.

min_seconds

Generation time below which replicates are not stored, because regenerating them is cheaper than reading them back.

Value

The generated replicates.
