4. What percentage of countries in Asia had a population of more than 50 million in 2007 (assign it to a4)? 5. What percentage of countries in Europe had a gdp per capita over $30,000 in 2007 (assign it to a5)?

Use R coding please

Answer 1

library(dplyr)

install.packages("gapminder")
library(gapminder)

a2 <- (gapminder %>% filter(continent == "Africa",year ==2007) %>% arrange(desc(gdpPercap)))[1,"gdpPercap"]
a2
a3 <- (gapminder %>% filter(continent == "Europe",year ==2007) %>% arrange(desc(gdpPercap)))[1,"gdpPercap"]
a3

a2 = 13206

a3 = 49357
