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 thename
argument, whereastar_branch_names_raw()
expects a character string forname
.- index
Integer vector of branch indexes.
- store
Character string, directory path to the
targets
data store of the pipeline.
