tar_dispatched: List dispatched targets.

In targets: Dynamic Function-Oriented 'Make'-Like Declarative Pipelines

List dispatched targets.

Description

List the targets with progress status "dispatched".

Usage

tar_dispatched(names = NULL, store = targets::tar_config_get("store"))

Arguments

names	Optional, names of the targets. If supplied, the function restricts its output to these targets. You can supply symbols or tidyselect helpers like any_of() and starts_with().
store	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.

Details

A target is "dispatched" if it is sent off to be run. Depending on your high-performance computing configuration via the crew package, the may not actually start right away. This may happen if the target is ready to start but all available parallel workers are busy.

Value

A character vector of dispatched targets.
