tar_progress_branches: Tabulate the progress of dynamic branches.

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

Tabulate the progress of dynamic branches.

Description

Read a project's target progress data for the most recent run of the pipeline and display the tabulated status of dynamic branches. Only the most recent record is shown.

Usage

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

Arguments

names	Optional, names of the targets. If supplied, tar_progress() only returns progress information on these targets. The object supplied to names should be NULL or a tidyselect expression like any_of() or starts_with() from tidyselect itself, or tar_described_as() to select target names based on their descriptions.
fields	Optional, names of progress data columns to read. Set to NULL to read all fields.
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.

Value

A data frame with one row per target per progress status and the following columns.

• name: name of the pattern.

• progress: progress status: "dispatched", "completed", "canceled", or "errored".

• branches: number of branches in the progress category.

• total: total number of branches planned for the whole pattern. Values within the same pattern should all be equal.

Examples

if (identical(Sys.getenv("TAR_EXAMPLES"), "true")) { # for CRAN
tar_dir({ # tar_dir() runs code from a temp dir for CRAN.
tar_script({
  library(targets)
  library(tarchetypes)
  list(
    tar_target(x, seq_len(2)),
    tar_target(y, x, pattern = map(x)),
    tar_target(z, stopifnot(y < 1.5), pattern = map(y))
  )
}, ask = FALSE)
try(tar_make())
tar_progress_branches()
})
