find immediate omop concept relations of one passed ADVISORY instead to use omop_relations() with default nsteps=1 arg.

Usage

omop_relations1step(
  c_id = NULL,
  c_ids = NULL,
  d_ids = NULL,
  v_ids = NULL,
  cc_ids = NULL,
  standard = NULL,
  r_ids = NULL,
  itself = FALSE,
  names2avoid = c("SNOMED CT core", "Defined", "Primitive"),
  join_names = TRUE,
  messages = TRUE
)

Arguments

c_id: single omop concept_id or exact concept_name to get relations of, default NULL returns all
c_ids: one or more concept_id to filter by, default NULL for all
d_ids: one or more domain_id to filter by, default NULL for all
v_ids: one or more vocabulary_id to filter by, default NULL for all
cc_ids: one or more concept_class_id to filter by, default NULL for all
standard: one or more standard_concept to filter by, default NULL for all, S,C
r_ids: one or more relationship_id to filter by, default NULL for all, e.g c('Is a','Subsumes')
itself: whether to include relations to concept itself, default=FALSE
names2avoid: concept names to avoid, defaults to generic concepts with lots relations, can be set to NULL
join_names: whether to join concept names onto ids, default TRUE, FALSE used by omop_relations() to speed up
messages: whether to print info messages, default=TRUE

Value

a dataframe of concepts and attributes
