build_graph: Function build_graph

Description

Make a graph of the dependency structure of your workplan.

Usage

build_graph(plan = workplan(), targets = drake::possible_targets(plan),
  envir = parent.frame(), verbose = TRUE, jobs = 1)

Arguments

plan

workflow plan data frame, same as for function make().

targets

names of targets to build, same as for function make().

envir

environment to import from, same as for function make().

verbose

logical, whether to output messages to the console.

jobs

number of jobs to accelerate the construction of the dependency graph. A light mclapply-based parallelism is used if your operating system is not Windows.

Details

This function returns an igraph object representing how the targets in your workplan depend on each other. (help(package = "igraph")). To plot the graph, call to plot.igraph() on your graph, or just use plot_graph() from the start.
