Main Client

The main entry point is the OMOPHubClient R6 class which provides access to all API resources:

library(omophub)
client <- OMOPHubClient$new()

# Search for concepts
results <- client$search$basic("diabetes")

# Get a specific concept
concept <- client$concepts$get(201826)

Authentication

Set your API key using one of these methods:

• Environment variable: OMOPHUB_API_KEY

• Explicit argument: OMOPHubClient$new(api_key = "your_key")

• Keyring: set_api_key("your_key", store = "keyring")

Resources

The client provides access to these resources:

• concepts: Concept lookup and batch operations

• search: Basic and advanced concept search

• vocabularies: Vocabulary listing and details

• domains: Domain listing and concept filtering

• hierarchy: Ancestor and descendant navigation

• relationships: Concept relationships

• mappings: Concept mappings between vocabularies
