Read a project's target progress data for the most recent run of tar_make() or similar. Only the most recent record is shown.

  names = NULL,
  fields = "progress",
  store = targets::tar_config_get("store")



Optional, names of the targets. If supplied, tar_progress() only returns progress information on these targets. You can supply symbols or tidyselect helpers like all_of() and starts_with().


Optional, names of progress data columns to read. Set to NULL to read all fields.


Character of length 1, path to the targets data store. Defaults to tar_config_get("store"), which in turn defaults to _targets/. When you set this argument, the value of tar_config_get("store") is temporarily changed for the current function call. See tar_config_get() and tar_config_set() for details about how to set the data store path persistently for a project.


A data frame with one row per target and the following columns:

  • name: name of the target.

  • type: type of target: "stem" for non-branching targets, "pattern" for dynamically branching targets, and "branch" for dynamic branches.

  • parent: name of the target's parent. For branches, this is the name of the associated pattern. For other targets, the pattern is just itself.

  • branches: number of dynamic branches of a pattern. 0 for non-patterns.

  • progress: the most recent progress update of that target. Could be "started", "built", "skipped", "canceled", or "errored".
