get_pop_query: Get Population Data

In onemapsgapi: R Wrapper for the 'OneMap.Sg API'

Get Population Data

Description

This function is a wrapper for the Population Query API. It only allows for querying of one data type (i.e. one of the API endpoints) for a particular town and year.

Usage

get_pop_query(token, data_type, planning_area, year, gender = NULL)

Arguments

token	User's API token. This can be retrieved using get_token
data_type	Type of data to be retrieved, should correspond to one of the API endpoints. E.g. to get economic status data, data_type = "getEconomicStatus". The API endpoints can be found on the documentation page.
planning_area	Town for which the data should be retrieved.
year	Year for which the data should be retrieved.
gender	Optional, valid values include male and female. If specified, only records for that gender will be returned. This parameter is only valid for the "getEconomicStatus", "getEthnicGroup", "getMaritalStatus" and "getPopulationAgeGroup" endpoints. If specified for other endpoints, the parameter will be dropped. If gender is not specified for valid endpoints, records for total, male and female will be returned.

Value

A tibble with 1 row and values for all the corresponding variables returned by the API endpoint. If an error occurs, the function will return a NULL value
