A run context created by r4subcore::r4sub_run_context().

config

A configuration list from usability_config_default(). If NULL the default configuration is used.

Examples

ctx <- suppressMessages(r4subcore::r4sub_run_context(study_id = "STUDY01"))
ev  <- suppressMessages(assess_label_quality(r4subdata::adam_metadata, ctx))
table(ev$result)
