tar_branch_names: Branch names

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

Branch names

Description

Get the branch names of a dynamic branching target using numeric indexes. tar_branch_names() expects an unevaluated symbol for the name argument, whereas tar_branch_names_raw() expects a character string for name.

Usage

tar_branch_names(name, index, store = targets::tar_config_get("store"))

tar_branch_names_raw(name, index, store = targets::tar_config_get("store"))

Arguments

name	Name of the dynamic branching target. tar_branch_names() expects an unevaluated symbol for the name argument, whereas tar_branch_names_raw() expects a character string for name.
index	Integer vector of branch indexes.
store	Character string, directory path to the targets data store of the pipeline.

Value

A character vector of branch names.

  list(
    tar_target(x, seq_len(4)),
    tar_target(y, 2 * x, pattern = map(x)),
    tar_target(z, y, pattern = map(y))
  )
}, ask = FALSE)
