[Query] Dataflow Cluster

Generated from 'wiki-query.ts' on 2026-11-08, 11:35:56 UTC (v2.17.4), do not edit directly.

Calculates and returns all the clusters present in the dataflow graph.
This query is requested with the type dataflow-cluster.

This query automatically calculates clusters in flowR's dataflow graph and returns a list of all clusters found. Clusters are to be interpreted as literal clusters on the graph traversing edges in both directions. From this perspective, the code x <- 1; x has one cluster (given that all code is related), while the code x <- 1; y has two clusters (given that the y has no relation to the previous definition).

[ { "type": "dataflow-cluster" } ]

{"dataflow-cluster":{".meta":{},"clusters":[{"startNode":3,"members":[3,0,2,1],"hasUnknownSideEffects":false}]},".meta":{}}

[ { "type": "dataflow-cluster" } ]

{"dataflow-cluster":{".meta":{},"clusters":[{"startNode":3,"members":[3],"hasUnknownSideEffects":false},{"startNode":2,"members":[2,1,0],"hasUnknownSideEffects":false}]},".meta":{}}

Using the example code from above, the following query returns all clusters:

[ { "type": "dataflow-cluster" } ]

(This can be shortened to @dataflow-cluster when used with the REPL command :query).
