Hint: You can choose any data you like but can’t take one that is already taken by other groups.

library(tidyverse)
seattle_pets <- read_csv("seattle_pets.csv")
library(vcd)

Explain data

Hint: Source and description of data, and definition of variables.

The source of the data is articles on the most popular pet names in 2018. This article specifically is from Seattle. The variables are the date the animal was registered with Seattle, the unique license number, the animal’s name, animal’s species, the primary breed of the animal, the secodary breed if it is mixed, and the zip code the animal is refistered under.

Visualize data

Hint: Create at least two plots.

library(ggplot2)
data(seattle_pets)

Seattle_animals <- filter(seattle_pets, 
                  species == "Dog" | 
                  species == "Cat")
# plot the distribution of race
ggplot(Seattle_animals, aes(x = species)) + 
  geom_bar()

Seattle_animals <- 
  Seattle_animals %>%
  mutate(primary_breed = fct_lump(primary_breed, 10))

library(ggplot2)

# stacked bar chart
ggplot(Seattle_animals, 
       aes(x = species, 
           fill = primary_breed)) + 
  geom_bar(position = "stack")

Correlation and regression analysis

Seattle_animal_zip <- 
  Seattle_animals %>%
  mutate(zip_code = fct_lump(zip_code, 5))


tbl <- xtabs(~species + zip_code, Seattle_animal_zip)
ftable(tbl)
##         zip_code 98103 98115 98117 98122 98125 Other
## species

library(vcd)
mosaic(tbl,
