Create a country-level choropleth using data from the World Bank's World Development Indicators (WDI)
choroplethr_wdi(
code = "SP.POP.TOTL",
year = 2012,
title = "",
num_colors = 7,
zoom = NULL
)
A choropleth.
The WDI code to use.
The year of data to use.
A title for the map. If not specified, automatically generated to include WDI code and year.
The number of colors to use on the map. A value of 1 will use a continuous scale, and a value in [2, 9] will use that many colors.
An optional list of countries to zoom in on. Must come from the "name" column in ?country.regions.
Uses the WDI function from the WDI package by Vincent Arel-Bundock.
