Description Usage Arguments Details Value References Examples

This function wraps all other get_ and .get_ functions to retrieve and store in a single object all the information relative to a particular entity in the European Pollen Database (EPD).

1	get_entity(e_, connection)

`e_`	numeric Number indicating the identification number (e_) of the entity that is desired. If multiple numbers are passed the function retrieves data only for the first one.
`connection`	PostgreSQLConnection A valid PostgreSQL connection to the EPD database server.

The function also import in the objects information from Giesecke et al. (2013), if available for that entity. The chronology used by Giesecke are numbered as 9999 to distinguish them from those stored in the EPD. It also check the geographical location of the entity and import the postbomb zone of the world.

The function returns an epd.entity-class object, which countains several objects with several tables.
