Assignment 6

Author

Go to the shared posit.cloud workspace for this class and open the assign06 project. Open the assign06.qmd file and complete the exercises.

This is a very open-ended assignment. There are three musts:

  1. You must use the tidycensus package to get either decennial or ACS data from the US Census Bureau.

  2. You must get data for two different variables and they can’t be population or median home values.

  3. You must show all the code you used to get the data and create the table or chart.

You can then either create a cool table or chart comparing the two variables. They can be from any region and for any geography…it doesn’t necessarily need to be Maine.

Note: you will receive deductions for not using tidyverse syntax in this assignment. That includes the use of filter, mutate, and the up-to-date pipe operator |>.

The Grading Rubric is available at the end of this document.

We’ll preload the following potentially useful packages

library(tidyverse)
library(tidycensus)
library(gapminder)
library(gt)
library(gtExtras)
library(scales)
ne_income <- get_acs(geography = "state",
                     variables = "B19013_001", 
                     survey = "acs1", 
                     state = c("ME", "NH", "VT", "MA", 
                               "RI", "CT", "NY"))
Getting data from the 2022 1-year ACS
The 1-year ACS provides data for geographies with populations of 65,000 and greater.
Warning: • You have not set a Census API key. Users without a key are limited to 500
queries per day and may experience performance limitations.
ℹ For best results, get a Census API key at
http://api.census.gov/data/key_signup.html and then supply the key to the
`census_api_key()` function to use it throughout your tidycensus session.
This warning is displayed once per session.
ggplot(ne_income, aes(x = estimate, y = reorder(NAME, estimate))) + 
  geom_point()

g_color <- ggplot(ne_income, aes(x = estimate, y = reorder(NAME, estimate))) + 
  geom_point(color = "maroon", size = 4)


g_scale <- g_color + 
  scale_x_continuous(labels = scales::dollar) + 
  theme_minimal(base_size = 12) 


g_label <- g_scale + 
  labs(x ="2016 ACS estimate", 
       y = "", 
       title = "Median household income by state")

g_label

This is your work area. Add as many code cells as you need.
