Create a new extraction plan

Initialises an empty omop_plan object that serves as the container for cohort definitions, output specifications, and plan-wide options. Build up the plan by piping it through ds.omop.plan.* helpers such as ds.omop.plan.cohort, ds.omop.plan.baseline, and ds.omop.plan.events.

Usage

ds.omop.plan()

Value

An omop_plan object (a list with class c("omop_plan", "list")) containing empty slots for cohort, anchor, outputs, and options.

plan <- ds.omop.plan()
plan <- ds.omop.plan.cohort(plan, cohort_definition_id = 1)
plan <- ds.omop.plan.baseline(plan)
} # }
