flow (version 0.2.0)

flow_view_uses: Show graph of callers of a function

Description

Experimental function that displays for a given object or function all functions that call it directly or indirectly.

Usage

flow_view_uses(x, pkg = NULL, out = NULL)

Value

flow_view_uses() returns a "flow_diagram" object by default, and the output path invisibly if out is not NULL (called for side effects).

Arguments

x

An object

pkg

A package or environment to fetch callers from, by default fun's environment

out

a path to save the diagram to. Special values "html", "htm", "png", "pdf", "jpg" and "jpeg" can be used to export the object to a temp file of the relevant format and open it, if a regular path is used the format will be guessed from the extension.

Details

The function is not very robust yet, but already useful for many usecases.
