data(cities500)

The GeoLocation variable has (lat, long) format

Split GeoLocation (lat, long) into two columns: lat and long

latlong <- cities500|>
  mutate(GeoLocation = str_replace_all(GeoLocation, "[()]", ""))|>
  separate(GeoLocation, into = c("lat", "long"), sep = ",", convert = TRUE)

Filter the dataset

Remove the StateDesc that includes the United Sates, select Prevention as the category (of interest), filter for only measuring crude prevalence and select only 2017.

latlong_clean <- latlong |>
  filter(StateDesc != "United States") |>
  filter(Data_Value_Type == "Crude prevalence") |>
  filter(Year == 2017) |>

The new dataset “Prevention” is a manageable dataset now.

For your assignment, work with a cleaned dataset.

1. Once you run the above code and learn how to filter this complicated dataset, perform your own investigation by filtering this dataset however you choose so that you have a subset with no more than 900 observations.

Filter chunk here (you may need multiple chunks)

#filter the data by binge drinking
ct_binge_drinking <- filter(latlong_clean2, MeasureId == "BINGE")

view(ct_binge_drinking)
ct_binge_drinking_clean <- ct_binge_drinking[, c(2,4,10,11,12,13)]
ct_binge_drinking_clean
# A tibble: 228 × 6

 3 CT        Stamford         16.1            4896  41.1 -73.6
 4 CT        Danbury          17.7            5305  41.4 -73.4
 5 CT        Bridgeport       16.3            2836  41.2 -73.2

 8 CT        Stamford         17.4          122643  41.1 -73.6
 9 CT        Stamford         16.5            6303  41.0 -73.5
10 CT        Hartford         10.4            1622  41.8 -72.7
# ℹ 218 more rows

2. Based on the GIS tutorial (Japan earthquakes), create one plot about something in your subsetted dataset.

First plot chunk here

# non map plot, binge drinking in CT
ggplot(ct_binge_drinking_clean) +
  geom_bar(aes(x = CityName))

ct_binge_drinking_clean2 <- ct_binge_drinking_clean |>
  group_by(CityName, Data_Value) |>
  summarise(
    avg_pop = mean(PopulationCount),
     .groups = "drop")
  ggplot(ct_binge_drinking_clean2, aes(x=Data_Value, y=avg_pop, color = CityName)) +
  geom_point(alpha = 0.4) +
  labs(title = "Binge Drinking in CT by City",
       caption = "Source: CDC") + 
  facet_wrap(~CityName) +
  scale_color_viridis_d("City") +
  theme_bw()

#long and lat of CT
ct_lon <- -72.7
ct_lat <- 41.6

3. Now create a map of your subsetted dataset.

First map chunk here

leaflet() |>
  setView(lng = -72.7, lat = 41.6, zoom = 6) |>
  addProviderTiles("Esri.WorldStreetMap")|> 
  addCircles( data = ct_binge_drinking,
              radius = ct_binge_drinking_clean2$avg_pop)
Assuming "long" and "lat" are longitude and latitude, respectively

4. Refine your map to include a mouse-click tooltip

class("long")
[1] "character"

Refined map chunk here

#convert lat and long to numeric
ct_binge_drinking_clean3 <- ct_binge_drinking_clean %>% 
  mutate(across(c("lat", "long"), as.numeric))
library(leaflet)
leaflet() |>
  setView(-72.7, lat = 41.6, zoom = 10) |>
  addProviderTiles("Esri.WorldStreetMap") |> 
  addCircles(
    data = ct_binge_drinking_clean3,
    lng = ~long,
    lat = ~lat,
    #radius = ~PopulationCount,
    popup = ~paste0(CityName, Data_Value)
  )

5. Write a paragraph

This leaflet looks at the data_value or percent of adults who binge drink in Connecticut’s biggest cities. In order to create this GIS plot, I further filtered and cleaned the data until I only had instances of binge drinking in cities in Connecticut and extracted the following variables: state, city, population, data_value, latitude, and longitude. I then followed the GIS Exploration tutorial from class, to create a version with this data.
