A graph showing all Flow objects heritage is calculated, and displayed.
graph_flow(env = .GlobalEnv, child_to_parent = TRUE, plotit = TRUE, ...)Arguments
- env
The environment to look for Flow objects. By default, it is
.GlobalEnv, and you should not change it, since all Flow objects are derived from it by construction.- child_to_parent
Do the arrows go from child to parent (by default), or in the other direction?
- plotit
Do we plot the graph (by default)?
- ...
Further parameters passed to
plot.igraph().
Value
An igraph object (returned invisibly if plotit = TRUE.
