Exoplanet: Exoplanet: Access to NASA's Exoplanet Archive database

In Liu-Zhichao/nasaR: Interface to Various NASA APIs

Description

This function allows programatic access to NASA's Exoplanet Archive database. See detailed info at: https://exoplanetarchive.ipac.caltech.edu/docs/program_interfaces.html#data.

Usage

Exoplanet(table = "exoplanets", select = NULL, count = NULL,
  colset = NULL, where = NULL, order = NULL, ra = NULL,
  dec = NULL, radius = NULL, aliastable = NULL)

Arguments

table	String. Specifies which table to query. "exoplanets" as default. Check the website for a full list of tables.
select	String. Specifies which columns within the chosen table to return. Check the website for valid column names.
count	Integer. Can be used to return the number of rows which fulfill the given query, including queries using where clauses or cone searches.
colset	String. Returns a set of pre-defined columns that have been created by the archive. Currently, this keyword is only used by the Composite Planet Data (compositepars) table.
where	String/A vector of strings. Specifies which rows to return. Use this to search for a range of values, such as rows with a declination greater than 0. Parameters must use a valid column name.
order	String. Controls the order the rows are returned.
ra	Number. Specifies an area of the sky to search for all objects within that area. Right Ascension (ra), Declination (dec) and radius (radius or rad) must be listed with their respective coordinates or units.
dec	Number. Specifies an area of the sky to search for all objects within that area. Right Ascension (ra), Declination (dec) and radius (radius or rad) must be listed with their respective coordinates or units.
radius	String. Specifies an area of the sky to search for all objects within that area. Right Ascension (ra), Declination (dec) and radius (radius or rad) must be listed with their respective coordinates or units. The units must be included in the radius specification (degrees, minutes, arcsecs) with a space preceding the unit name.
aliastable	String. Requests a list of aliases for a particular confirmed planet.

Value

Data from NASA's Exoplanet Archive database.

Examples

Exoplanet()
Exoplanet(select = "pl_hostname", order = "dec")
Exoplanet(ra = 291, dec = 48, radius = "1 degree")
Exoplanet(table = "cumulative", where = c("koi_prad<2", "koi_teq>180", "koi_teq<303", "koi_disposition like 'CANDIDATE'"))
Exoplanet(aliastable = "bet Pic")
