Simulate Synthetic Section Data From a Schema Mapping

Source: R/simulate_cohort.R
simulate_section_data.Rd

Generates synthetic data honoring the column roles declared in a validated mapping table. If the pslongSim package is available, it is leveraged for baseline subject scaffolding; otherwise, an internal robust generator produces demographic and longitudinal grids.

Usage

simulate_section_data(
  mapping,
  index,
  n_subjects = 20,
  seed = 1,
  missing_rate = 0,
  time_levels = NULL
)

Arguments

mapping

Validated column mapping table; see validate_column_mapping.

index

Character string identifying the section/domain in mapping$INDEX to simulate.

n_subjects

Number of synthetic subjects to generate (default: 20).

seed

Random seed for reproducibility (default: 1).

missing_rate

Probability in [0, 1] that any non-ID, non-time cell is set to NA.

time_levels

Optional character vector of levels for the section's Time_var column (default: c("T0", "T1", "T2", "T3")).

Value

A tibble shaped according to the standardized new columns for the specified section.
