epd.entity-class: Class for epd.entity objects

Description Details Slots References

Description

This object stores all the information available for a particular entity in the European Pollen Database (EPD). It has some additional information (e.g., in @postbombzone or @isingiesecke slots). Other slots store handy information for simplicity (e.g., @defaultchron or @numberofchron slots). The rest of slots are the raw information as extracted from the EPD, and stored in the link[EPDr]{entity}, link[EPDr]{site}, link[EPDr]{geochron}, link[EPDr]{chron}, and link[EPDr]{samples} classes.

Details

All data in this object can be changed, but the intention of the object is to provide a copy of all the tables in the EPD with information regarding a particular entity. When an entity has no data in any particular table, the table is created empty.
