Use of drake_config()

[wlandau]

@DominikRafaczk, I would just like to point out a minor detail on slide 6. Contrary to intuition, problems can arise when you call

vis_drake_graph(drake_config(plan))

or

drake_config(plan) %>%
  vis_drake_graph()

rather than the more reliable

config <- drake_config(plan)
vis_drake_graph(config)

Details: ropensci/drake#163, ropensci/drake#335, ropensci/drake#527, ropensci/drake#874.

To avoid this issue altogether, you can define a _drake.R file and use r_make() and r_vis_drake_graph() instead: https://ropenscilabs.github.io/drake-manual/projects.html#safer-interactivity

Thanks for pointing it out. I'm just learning how to use drake and it seems that I need to learn a lot more...
I've changed the code according to your suggestion.

Thanks!
