Getting Started with normanR

This vignette demonstrates how to retrieve chemical and ecotoxicological data from the Norman Network REST API using the core get_norman_data() function across its supported modules (susdat, ecotox, empodat, and passive). Additional package features include batch querying (get_norman_data_multi(), get_norman_empodat_batch_data()), flattening nested JSON outputs into data frames (extract_norman_fields()), loading API metadata definitions (load_api_definitions()), and partitioning local JSON files into subfolders (split_json_files_by_key(), split_json_files_by_pattern()).

# Fetch substance data by CAS number using the core function

  module = "susdat",
  parameter = "casrn",
  value = "1490-04-6",
  format = "json"
)
