Local data and development • ComptoxR

Local database copies support repeated queries, offline work, and controlled data extraction. Downloads can be large. Install only the database that your work needs.

Install local databases

library(ComptoxR)

dss_install()
eco_install()
toxval_install()

Use source, tag, or overwrite only when you need a specific release or must replace an existing copy. See each function reference for its current options.

Check health and schema before querying

eco_health()
eco_tables()
eco_fields("results")
eco_inventory()

toxval_health()
toxval_tables()
toxval_fields("toxval")
toxval_sources()

The health result identifies the configured local data source. Table and field functions help you confirm the schema before a large query.

Use the focused articles

See Hazard Data and ToxValDB for local toxicity values and ECOTOX for ecological effects. DSSTox provides local chemical search and resolution:

dss_search("benzene", limit = 20)
dss_resolve("71-43-2")

Develop ComptoxR

Read the standalone development lifecycle before changing the package. It describes branches, checks, continuous integration, and releases. Also read CONTRIBUTING.md in the repository root. Do not record API cassettes unless the task requires production traffic and you can run the cassette safety checks.
