Part 4: Custom Functions extra text

[CheFusi]

" # every time we would have written the continent, we now write 'cont'"

should be removed - not used

[CheFusi]

Happens in the portion of script right before the Key Points (shown below). In this chunk of script, " # here we use the paste0() function to allow cont to change in the title" is text that also should be removed

"
lifeexp_plot <- function(country_name){

function plotting life expectancy against over time by country

country_name = name of country, string

every time we would have written the continent, we now write cont

p <- gap %>%
filter(country == country_name) %>%
ggplot(aes(x = year, y = lifeExp)) +
geom_point() +
# here we use the paste0() function to allow cont to change in the title
ggtitle(paste0("Life expectancy over time in ", country_name)) +
ylab("Life expectancy (years)") +
xlab("Year") +
theme_bw()

return the plot so it prints out when we call the function

return(p)
