Question 6You are working with the penguins dataset. You create a scatterplot with the following code: ggplot(data = penguins) +  geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g))You want to highlight the different years of data collection on your plot. Add a code chunk to the second line of code to map the aesthetic size to the variable year.

You are working with the penguins dataset. You create a scatterplot with the following code:ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g)) +You want to use the labs() function to add the title “Penguins” to your plot. Add the code chunk that lets you add the title "Penguins" to your plot.

Question 10You are working with the penguins dataset. You create a scatterplot with the following lines of code: ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g)) + What code chunk do you add to the third line to save your plot as a pdf file with “penguins” as the file name? 1 pointggsave(“penguins.pdf”)ggsave(penguins.pdf)ggsave(=penguins)ggsave(“pdf.penguins”)

A data analyst is working with the penguins data. The analyst creates a scatterplot with the following code: ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g, alpha = species))What does the alpha aesthetic do to the appearance of the points on the plot? 1 pointMakes the points on the plot larger Makes some points on the plot more transparentMakes the points on the plot smallerMakes the points on the plot more colorful
