gapminder

The is a data package with an excerpt from the Gapminder data.
The main object in this package is the gapminder data frame or “tibble”.
There are other goodies, such as the data in tab delimited form, a larger unfiltered dataset, premade color schemes for the countries and continents, and ISO 3166-1 country codes.
The primary use case is for teaching and writing examples.

Installation

Install gapminder from CRAN:

install.packages("gapminder")

Quick look

Here we do a bit of data aggregation and plotting with the gapminder data:

library(gapminder)
library(dplyr)
library(ggplot2)

aggregate(lifeExp ~ continent, gapminder, median)

gapminder %>%
  filter(year == 2007) %>%
  group_by(continent) %>%
  summarise(lifeExp = median(lifeExp))

ggplot(gapminder, aes(x = continent, y = lifeExp)) +
  geom_boxplot(outlier.colour = "hotpink") +
  geom_jitter(position = position_jitter(width = 0.1, height = 0), alpha = 1 / 4)
