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

# \donttest{
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")
#> [1] "Is a"        "Mapped from" "Maps to"     "Subsumes"
