Generate simulated datasets across scenario combinations (TXT/CSV/RDS/RData)

Builds a grid of scenarios from a base recipe and a named list of variations, simulates one or more replicates per scenario, and writes the datasets to files in a target folder as .txt (tab), .csv, .rds, and/or .RData. A manifest is written as manifest.rds. No YAML and no L/tau.

Usage

generate_recipe_sets(
  base_recipe,
  vary = list(),
  out_dir,
  formats = c("txt", "csv", "rds", "rdata"),
  n_reps = 1L,
  seed_base = NULL,
  filename_template = "sc{scenario_id}_r{rep}"
)

Arguments

base_recipe

A recipe list (use validate_recipe() if needed).

vary

Named list; keys are dotted paths inside the recipe (e.g., "n", "censoring.target", "event_time.effects.treatment").

out_dir

Directory to write datasets and manifest.rds (created if missing).

formats

Character vector subset of c("txt","csv","rds","rdata").

n_reps

Integer; number of replicates per scenario.

seed_base

Optional integer; per-rep seed computed as seed_base + scenario_id*1000 + rep.

filename_template

Base filename (no extension) with placeholders: "{scenario_id}", "{rep}" and any dotted path used in vary.

Value

Invisibly returns the manifest data.frame and writes manifest.rds.

Examples

covs <- list(list(name="x", type="continuous", dist="normal", params=list(mean=0, sd=1)))
rec <- recipe_quick_aft(60, "aft_lognormal",
         baseline=list(mu=2.7, sigma=0.6), treat_effect=-0.2,
         covariates=covs, target_censoring=0.2)
dir.create("checks", showWarnings = FALSE)
man <- generate_recipe_sets(rec, vary=list(n=c(60,80)), out_dir="checks",
         formats=c("csv","rds"), n_reps=1, seed_base=123)
