Get available relationships between concepts

Description

Get available relationships between concepts

Usage

availableRelationshipIds(
  cdm,
  standardConcept1 = "Standard",
  standardConcept2 = "Standard",
  domains1 = "Condition",
  domains2 = "Condition"
)

Arguments

cdm	A cdm reference to an OMOP CDM dataset. If data is held within a database, the vocabulary tables should be in the same schema as the clinical tables (person, observation period, and so on).
standardConcept1	Character vector with one or more of "Standard", "Classification", and "Non-standard". These correspond to the flags used for the standard_concept field in the concept table of the cdm.
standardConcept2	Character vector with one or more of "Standard", "Classification", and "Non-standard". These correspond to the flags used for the standard_concept field in the concept table of the cdm.
domains1	Character vector with one or more of the OMOP CDM domain. If NULL, all domains are considered.
domains2	Character vector with one or more of the OMOP CDM domain. If NULL, all domains are considered.

Value

A character vector with unique concept relationship values.

Examples

library(CodelistGenerator)
library(omock)

# Create CDM object
cdm <- mockCdmReference()

# Get all relationship ids in the CDM between `Condition` and `Standard` concepts.
availableRelationshipIds(cdm = cdm,
                         standardConcept1 = "Standard",
                         standardConcept2 = "Standard",
                         domains1 = "Condition",
                         domains2 = "Condition")
