Just installed latest version from Github 7.11.0.9000:

plan <- drake_plan(
  raw = mtcars,
  group_index = raw$cyl,
  munged = target(raw[, c("mpg", "cyl")], dynamic = map(raw)),
  mean_mpg_by_cyl = target(
    data.frame(mpg = mean(munged$mpg), cyl = munged$cyl[1]),
    dynamic = group(munged, .by = group_index)
  )
)
make(plan)

Error in refclass_logger$new(verbose = verbose, file = file, progress_bar = progress_bar) :

Installing the progress package fixes the issue. I meant to make drake work without progress, but I guess I goofed. Patch forthcoming.

[mbacou]

Thanks, had to install progress and visNetwork. Problem resolved!

[wlandau]

In 8d34019 and later, drake should work without the progress package. I assume you needed visNetwork for vis_drake_graph()? Hopefully the error was informative that time.

[mbacou]

Correct, vis_drake_graph error was straightforward.
