Targets Tips

This document lists useful tips for targets package function usage.

tar_load_globals()

• tar_load_globals()loads user-defined packages, functions, global objects, and settings defined in the target script file (default: _targets.R). This function is for debugging, testing, and prototyping only. It is not recommended for use inside a serious pipeline or to report the results of a serious pipeline.

tar_workspace()

• tar_workspace() only works if  you tell targets to save the workspace for that target. Which means the target has to be explicitly named in tar_option_set(workspace = c("target_name_one","target_name_two"))
• However, tar_option_set(workspace_on_error = TRUE) saves the workspace if the target errors.
• So say target target_name_one errors, you could do tar_workspace(target_name_one) and it will load that workspace and you can debug it there.

tar_load()

• tar_load() works with tidy selectors.

# So you can do this:
tar_load(c(reference_group_local, focal_group_local, gender_label))

# or this:
tar_load(ends_with("local"))
