makeMeta: Create a metadata object table for a set of charts

In safetyGraphics: Interactive Graphics for Monitoring Clinical Trial Safety

Create a metadata object table for a set of charts

Description

Generates metadata object for a list of charts. makeMeta() looks for metadata in 3 locations for each chart object:

• Domain-level metadata saved as meta_chart$name in the chart$package namespace

• Chart-specific metadata saved as meta_chart$domain in the chart$package namespace

• Chart-specific metadata saved directly to the chart object as chart$meta After checking all charts, all metadata files are stacked in to a single dataframe and returned. If duplicate metadata rows (domain + text_key) are found, an error is thrown.
