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.

Usage

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

Arguments

name	Symbol, name of the dynamic branching target (pattern).
index	Integer vector of branch indexes.
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 character vector of branch names.

    tar_target(y, 2 * x, pattern = map(x)),
    tar_target(z, y, pattern = map(y))
  )
}, ask = FALSE)
tar_make()
tar_branch_names(z, c(2, 3))
