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)

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

First plot chunk here

# non map plot
graph1<-ggplot(cut, aes(Year, High_Confidence_Limit, color=Measure))+  scale_color_viridis_d()+ geom_jitter(alpha=0.5) + labs(title="High Confidence Limits for Different Measures in Baltimore", subtitle = "In 2016 and 2017")
graph1
Warning: Removed 5 rows containing missing values or values outside the scale range
(`geom_point()`).

3. Now create a map of your subsetted dataset.

First map chunk here

library(leaflet)
library(tidyverse)
library(ggplot2)
library(knitr)
library(webshot2)

latlong <-cities|>
  mutate(GeoLocation = str_replace_all(GeoLocation, "[()]", ""))|>
  separate(GeoLocation, into = c("lat", "long"), sep = ",", convert = TRUE)
Balt_lon<-76.6122
Balt_lat<-39.2904
# leaflet()
leaflet(data = cut) |>
  addProviderTiles("Esri.WorldStreetMap") |>
  setView(lng = -76.6122, lat = 39.2904, zoom = 11) |>
  addCircles(radius = 2, fillColor ="blue", fillOpacity = 0.25)
Assuming "long" and "lat" are longitude and latitude, respectively

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

Refined map chunk here

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

popupquake <- paste0(
  "<b>Year: </b>", cut$Year, "<br>",
  "<b>City: </b>", cut$CityName, "<br>",
  "<b>Category: </b>", cut$Category, "<br>",
  "<strong>Measure: </strong>", cut$Measure, "<br>",
  "<strong>High Confidence Limit: </strong>", cut$High_Confidence_Limit, "<br>"
)

leaflet(data = cut) |>
  addProviderTiles("Esri.WorldStreetMap") |>
  setView(lng = -76.6122, lat = 39.2904, zoom = 11) |>
  addCircles(radius = 2,fillColor ="blue", fillOpacity = 0.25,
             popup = popupquake)
Assuming "long" and "lat" are longitude and latitude, respectively

5. Write a paragraph

In a paragraph, describe the plots you created and what they show.

The plots I created was initially a scatter plot that showed the different measures of unhealthy behaviors in Maryland (all in which are in Baltimore) in 2016 and 2017 and their high confidence levels. In 2016, there was quite a high confidence limit in the lack of sleep people over 18 were getting. In 2017, there was quite a high confidence limit in adults that didn’t have any leisure time for physical activity and obesity. In 2017, the lowest high confidence limit was for adults binge drinking. I was also able to make the map without and with the interactive mouse click tooltip. When clicking on one of the points, you will see information of the year (2016 or 2017), city (Baltimore), category (Unhealthy behaviors), measure, and high confidence limit.
