Enforce full-coverage feasibility for sparse MET allocation

Internal function called by allocate_sparse_met() to verify that the supplied n_test_entries_per_environment provides enough sparse slots to assign every non-common treatment at least once. Stops with an informative error when the condition is not met.

Usage

.check_full_coverage_feasibility(
  treatments,
  environments,
  n_test_entries_per_environment,
  common_treatments = character(0)
)

Arguments

treatments

Character vector of all treatment IDs.

environments

Character vector of environment names.

n_test_entries_per_environment

Integer scalar or integer vector.

common_treatments

Character vector of common treatment IDs.

Value

Invisibly returns TRUE when the condition is satisfied.

Details

Unlike warn_if_k_too_small(), this function stops rather than warns and is not intended for direct use.
