Week 2 HW

Your objective is to replicate these figures, created using the Cooperative Congressional Election Study data. These figures are similar to those we completed in the lecture videos.

Exercise 1

Hints:

• For the x-axis, use the variable “ideo5”.

• Make sure you recode the data for the “ideo5” variable to generate the correct names for the x-axis. You will want to consult the codebook.

• Use the fill aesthetic to have R fill in the bars. You do not need to set the colors manually.

• Use guides() to drop the legend.

• Make sure the axis labels and figure title are correct.

Exercise 2

Hints:

• For the x-axis, use the variable “pew_religimp”.

• Make sure you recode the data for the “pew_religimp” variable to generate the correct labels for the x-axis. You will want to consult the codebook.

• Rename the column for Ideology to make sure the first letter is upper-case (to make the legend appear correctly).

• Use the fill aesthetic to have R fill in the bars. You do not need to set the colors manually.

• Make sure the axis labels and figure title are correct.

Exercise 3

Instructions:

• For this visualization, you are creating your own data for practice.

• Create a tibble/data frame with three columns: Semester, Student, and Grade.

• There should be six semesters and three students (Amanda, Betty, and Carol)

• Create grades for the students using the runif() command, with values between 80 and 100. Hint: you’ll need 18 grades total.

The figure should look approximately like this (your vaules will be slightly different):
