A list of data frames and settings containing metadata that will be used for
the application. The metadata will be merged with with raw data. It controls
the variables that will be used in the application, and in which tab the
variables will be shown. The goal is that most, if not all, study-specific
data will be captured in the metadata, leaving the scripts to run the
application largely unaltered between studies.See vignette("Metadata") for
in-depth information.
