Get the integer indexes of individual branch names within their corresponding dynamic branching targets.

tar_branch_index(names, store = targets::tar_config_get("store"))



Character vector of branch names


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.


A named integer vector of branch indexes.
