calculate nodes and edges from omop hierarchy accepts output from either omop_ancestors(), omop_descendants() or omop_relations used by omop_graph(), you are only likely to want to use on it's own to a) separate calculation & visualisation so that you can join attributes for visualisation b) pass the nodes and edges to a different graph rendering package

Usage

omop_graph_calc(dfin)

Arguments

dfin

dataframe output from either omop_ancestors(), omop_descendants() or omop_relations

Value

list containing edges & nodes tables

Examples

bp <- omop_relations("Non-invasive blood pressure")
#> recursively querying concept relations of: Non-invasive blood pressure - may take more than a few seconds
#> step 1 of 1
#>    querying concept relations of: Non-invasive blood pressure - may take a few seconds
#> returning 8 concepts
listedges_nodes <- omop_graph_calc(bp)
