Extracts all unique values of an extra attribute occuring in this data frame.
Arguments
- data
An interaction data frame with extra_attrs column.
- key
The name of an extra attribute.
Value
A vector, most likely character, with the unique values of the extra attribute occuring in the data frame.
Details
Note, at the end we unlist the result, which means it works well for attributes which are atomic vectors but gives not so useful result if the attribute values are more complex objects. As the time of writing this, no such complex extra attribute exist in OmniPath.
