Visualizing World Development Indicators
20 Jun 2015Fetching Data from World Bank
The Package WDI (world development indicators) is used to fetch data from WDI.
We can search the data as follow:
# Load required libraries
library('WDI')
library(ggplot2)

Below we import the data on GDP per capita from years 1980 to 2013 from some countries and we show a simple plot of it: GDP per capita (constant 2000 US$).
dat <- WDI(indicator = c("NY.GDP.PCAP.KD"),
country = c("PT","ES", "US", "EU", "BR"),
start = 1980, end = 2013)
#
ggplot(dat, aes(year, NY.GDP.PCAP.KD, color = country)) +
geom_line() + geom_point() +
labs(x = "year", y = "GDP per capita") +
ggtitle("GDP per capita by Country (constant 2000 US$)")
