ggplot() and aes() basics in R Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a basic ggplot object with the data frame 'df'.

R Programming

p <- ggplot([1])

Drag options to blanks, or click blank then click option'

Adf

Bgeom_point()

Caes

Dggplot

💡 Hint

Common Mistakes

Using aes or geom_point() directly inside ggplot() without specifying data.

Passing the function ggplot itself as argument.

The ggplot() function needs a data frame as its first argument to know which data to use.

2fill in blank

medium

Complete the code to map the variable 'x_var' to the x-axis inside aes().

R Programming

p <- ggplot(df, aes(x = [1]))

Drag options to blanks, or click blank then click option'

Ax_var

Bgeom_point

Cdf

Dy_var

💡 Hint

Common Mistakes

Using a variable name that is not in the data frame.

Passing the whole data frame instead of a variable name.

Inside aes(), you specify the variable names from the data frame to map to aesthetics like x or y axes.

3fill in blank

hard

Fix the error in the code by completing the aes() mapping for both x and y variables.

R Programming

p <- ggplot(df, aes(x = [1], y = [2])) + geom_point()

Drag options to blanks, or click blank then click option'

Ax_var

Bgeom_point

Cy_var

Ddf

💡 Hint

Common Mistakes

Using geom_point inside aes().

Using the data frame name instead of variable names.

Both x and y inside aes() must be variable names from the data frame to plot points correctly.

4fill in blank

hard

Fill both blanks to create a scatter plot mapping 'height' to x and 'weight' to y.

R Programming

p <- ggplot(data = df, aes(x = [1], y = [2])) + geom_point()

Drag options to blanks, or click blank then click option'

Aheight

Bweight

💡 Hint

Common Mistakes

Swapping the variables for x and y.

Using variables not present in the data frame.

To plot height on the x-axis and weight on the y-axis, map these variable names inside aes().

5fill in blank

hard

Fill all three blanks to create a ggplot with data 'df', mapping 'age' to x, 'income' to y, and adding points.

R Programming

p <- ggplot([1], aes(x = [2], y = [3])) + geom_point()

Drag options to blanks, or click blank then click option'

Adf

Bage

Cincome

Dheight

💡 Hint

Common Mistakes

Using variable names outside of aes().

Mixing up the order of arguments.

The ggplot() function needs the data frame first, then inside aes() you map the variables for x and y axes.
