Build a concept set specification (client-only)

Creates a local omop_concept_set object that defines a set of OMOP concepts along with expansion rules. This is a client-side-only helper that does not contact any server; the resulting object is passed to ds.omop.concept.expand for server-side resolution.

Usage

ds.omop.concept.set(
  concepts,
  include_descendants = FALSE,
  include_mapped = FALSE,
  exclude = NULL
)

Arguments

concepts

Integer or numeric vector of seed concept IDs that form the base of the concept set.

include_descendants

Logical; if TRUE, all descendants of the seed concepts (via concept_ancestor) will be included when the set is expanded. Default: FALSE.

include_mapped

Logical; if TRUE, non-standard concepts mapped to the seed concepts (via concept_relationship) will be included when the set is expanded. Default: FALSE.

exclude

Integer or numeric vector of concept IDs to explicitly remove from the expanded set. NULL (the default) excludes nothing.

Value

An omop_concept_set object (a list with class c("omop_concept_set", "list")).

Examples

if (FALSE) { # \dontrun{
# Simple concept set with descendants
cs <- ds.omop.concept.set(c(201826, 316139), include_descendants = TRUE)

# Expand the concept set on the server
expanded <- ds.omop.concept.expand(cs)
} # }
