List available correspondence tables from online services

Source: R/correspondenceTableList.R

Returns a data frame listing available correspondence tables (mappings between statistical classifications) published by one or more supported online services.

Use this function to discover valid `prefix` and `ID_table` values before calling `retrieveCorrespondenceTable()`.

correspondenceTableList(endpoint = "ALL", showQuery = FALSE)

Arguments

endpoint

Character. Which service(s) to query. One or more of the supported endpoints (e.g. "CELLAR", "FAO"), or "ALL" to query all available services. Case-insensitive. If multiple endpoints are supplied (including "ALL"), a **named list** is returned; otherwise a single `data.frame`.

showQuery

Logical. If `TRUE`, the SPARQL queries used are emitted via `message()` (suppress with `suppressMessages()`).

Value

If a single endpoint is requested, a `data.frame` (one row per correspondence). If multiple endpoints are requested (including "ALL"), a **named list** of data frames, one per endpoint.

Details

Read-only queries; no side effects (no file writes or caching).
