List the vocabularies available on each server — ds.omop.vocab.vocabularies • dsOMOPClient

Returns the distinct vocabularies from the OMOP vocabulary table on each connected server (falling back to distinct vocabulary_id values on concept when the vocabulary table is not loaded). Vocabulary reference data carries no patient information, so this reader is not disclosure-gated and the per-site frames are pooled by set union (a vocabulary may exist on several servers).

Usage

ds.omop.vocab.vocabularies(symbol = "omop", conns = NULL, execute = TRUE)

Arguments

symbol: Character; the session symbol used when the OMOP connection was initialised (default: "omop").
conns: DSI connection object(s). If NULL (the default), the connections stored in the active session are used.
execute: Logical; if FALSE, returns a dry-run dsomop_result containing only the reproducible R code without contacting the servers.

Value

A dsomop_result. per_site holds each server's vocabulary frame; pooled is the de-duplicated union across servers.

Examples

if (FALSE) { # \dontrun{
vocabs <- ds.omop.vocab.vocabularies()
vocabs$pooled
} # }
