Overview
The goal of worldbank is to provide a simple interface to the World Bank API v2. The main difference to other packages is that it’s a modern implementation using the httr2 package without any other dependencies.
The worldbank package provides a set of functions to interact with various endpoints of the World Bank API. Each function is designed to retrieve specific types of data, making it easier to access and analyze World Bank datasets. Below is an overview of the available endpoints and their corresponding functions in the package:
-
Languages (
wb_language): Retrieves a list of all languages supported by the World Bank API. Useful for obtaining language-specific data. -
Lending Types (
wb_lending_type): Fetches information about different lending types as recognized by the World Bank. -
Income Levels (
wb_income_level): Allows users to access data about various income levels defined by the World Bank. -
Sources (
wb_source): Provides details about the different data sources available within the World Bank’s datasets. -
Topics (
wb_topic): Lists all topics covered by the World Bank API, helping users to narrow down their data search to specific areas of interest. -
Regions (
wb_region): Offers information on different geographical regions as categorized by the World Bank. -
Countries (
wb_country): Enables access to detailed data about individual countries, including socio-economic and developmental indicators. -
Country Indicators (
wb_country_indicator): Specific to retrieving indicators for a particular country or countries, allowing for more targeted data analysis. -
Indicators (
wb_indicator): This endpoint gives users access to a wide array of indicators used by the World Bank in its data analysis and reports.
