Examples

# Can only run if system dependencies are configured:
if (file.exists(Sys.getenv("RFACTS_PATHS"))) {
facts_file <- get_facts_file_example("contin.facts") # example FACTS file
out <- run_facts(
  facts_file,
  n_sims = 4,
  verbose = FALSE
)
# What results files do we have?
head(get_csv_files(out))
# Read all the "patients*.csv" files with `read_patients(out)`.
# For each scenario, we have files named
# patients00001.csv, patients00002.csv, patients00003.csv,
# and patients00004.csv.
read_patients(out)
