Usage

get_geochron(e_, connection)

.get_geochron(e_, connection)

.get_aar(e_, connection)

.get_c14(e_, connection)

.get_esr(e_, connection)

.get_ft(e_, connection)

.get_pb210(e_, connection)

.get_si32(e_, connection)

.get_tl(e_, connection)

.get_useries(e_, connection)

Arguments

e_	numeric. Value indicating the entity number (e_) of the database that is queried.
connection	PostgreSQLConnection. Object of class PostgreSQLConnection as returned by function connect_to_epd.

Details

All functions here are designed to retrieve information from a single entity. If multiple entity numbers are requested, the functions return data only for the first one. Each function retrieve data from a specific table or set of tables that are conveniently combined if necessary.

Value

Data frame with all information from specific tables in the EPD (see documentation of the EPD: http://www.europeanpollendatabase.net/data/downloads/image/pollen-database-manual-20071011.doc) for the requested entity. Columns names in the resulting data frames will vary among functions.

get_geochron

This function returns a geochron-class object, that store information from different tables for a particular entity.

.get_geochron

This functions returns a data.frame with information in in the GEOCHRON table for the specified entity. This corresponds with the common geochronological data for the entity that have been analysed for that particular entity.

.get_aar

This functions returns a data.frame with information in in the AAR table for the specified entity. This corresponds with Amino Acid Racemization data for datation samples.

.get_c14

This functions returns a data.frame with information in in the C14 table for the specified entity. This corresponds with C14 data for all radiocarbon samples that have been analysed for that particular entity.

.get_esr

This functions returns a data.frame with information in in the ESR table for the specified entity. This corresponds with Electron Spin Resonance data for datation samples.

.get_ft

This functions returns a data.frame with information in in the FT table for the specified entity. This corresponds with Fission Track data for datation samples.

.get_kar

This functions returns a data.frame with information in in the KAR table for the specified entity. This corresponds with Fission Track data for datation samples.

.get_pb210

This functions returns a data.frame with information in in the PB210 table for the specified entity. This corresponds with ^[210]Pb isotope data for datation samples.

.get_si32

This functions returns a data.frame with information in in the SI32 table for the specified entity. This corresponds with ^[32]Si (Silicon-32) data for datation samples.

.get_tl

This functions returns a data.frame with information in in the TL table for the specified entity. This corresponds with Thermoluminescence data for datation samples.

.get_useries

This functions returns a data.frame with information in in the USERIES table for the specified entity. This corresponds with Uranium-series data for datation samples.
