Istruzioni dell'esercizio

tidyr and ggplot2 are loaded in your workspace.

Esercizio pratico interattivo

Prova a risolvere questo esercizio completando il codice di esempio.

# View rydf
___ 

# View pop_proportion
___

# Gather on all variables except Race
rydfl <- ___(rydf, ___, names_to = "Year", values_to = "Count")

# Create a new adjusted count variable
rydfl$Adjusted_Count <- rydfl$Count / pop_proportion[rydfl$Race]

# Plot
ggplot(rydfl, aes(x = ___, y = ___, group = Race, color = Race)) + 
    geom_line()
