dr_validate()

With a table and contract, returns quality evidence. With a composed product or pipeline alone, checks its configuration and returns the definition. Preflight does not evaluate source callbacks or prove data quality.

Usage

dr_validate(data, contract = NULL, ...)

\method{dr_validate}{default}(
  data,
  contract,
  stage = "candidate",
  keep_agents = FALSE,
  keep_errors = FALSE,
  ...
)

Arguments

data: A data frame, lazy table, composed product or pipeline.
contract: Contract definition.
...: Arguments forwarded to a validation method.
stage: Label stored with each check, such as "ingest" or "candidate".
keep_agents: Retain interrogated pointblank agents as an in-memory attribute for dr_pointblank_report(). Defaults to FALSE.
keep_errors: Retain original R conditions in an in-memory dr_errors attribute. They can contain private data and are never persisted in the registry. Inspect with dr_quality_errors(). Defaults to FALSE.

Value

For data, a tibble with one row per check; only passed and warning permit publication. For a workflow, the validated definition.

Examples

contract <- dr_contract(
  "orders", version = "1.0.0",
  columns = c(order_id = "integer", amount = "numeric"), key = "order_id"
)
dr_validate(data.frame(order_id = 1:2, amount = c(25, 75)), contract)
