Discover indicators

library(healthatlas)

Let’s set our health atlas. For this example we will use the Chicago Health Atlas. We can do so by calling ha_set() with the Chicago Health Atlas URL.

ha_set("chicagohealthatlas.org")

If we need to check which health atlas we are using, we can use ha_get().

ha_get()
#> [1] "https://chicagohealthatlas.org/api/v1/"

We can list all the topics (aka indicators) present within Chicago Health Atlas by using ha_topics(). The most important column here is the topic_key. An individual topic_key can be used to identify a topic within subsequent functions.

topics <- ha_topics(progress = FALSE)

There may be a specific topic area you are interested in exploring. You can explore these topic areas using ha_subcategories().

subcategories <- ha_subcategories()

You can use a subcategory_key to subset the list of topics.

Once we have a topic or topics in mind, we can explore what populations, time periods, and geographic scales that data is available at by using ha_coverage(). Again, the most important columns here are the key columns which can be used to specify the data desired.

coverage <- ha_coverage("HCSFVAP", progress = FALSE)

Import tabular data

Now, we can import our data using ha_data() and specifying the keys we identified above.

ease_of_access <- ha_data(
  topic_key = "HCSFVAP",
  population_key = "",
  period_key = "2022-2023",
  layer_key = "neighborhood"
)

We can even specify multiple topics, populations, and periods to get data for. ha_data() will return a combined table with data for every combination of topic, population, and period requested. A warning will be given for every invalid combindation of topic, population, and period requested.

combinations_of_data <- ha_data(
  topic_key = c("POP", "UMP"),
  population_key = c("", "H"),
  period_key = c("2017-2021", "2018-2022", "invalid"),
  layer_key = "neighborhood"
)

If you want to mix and match topics, populations, years, or layers of data, I recommend creating a table of all the datasets you want, and purrr::pmap()-ing over the table.

library(tibble)
library(purrr)

# creating a table of data I want
metadata <- tribble(
  ~ topic_key, ~ population_key, ~ period_key, ~ layer_key,

  "HCSFVAP",   "",               "2020-2021",  "neighborhood",
  "UMP",       "H",              "2017-2021",  "neighborhood",

You can also set geometry = TRUE within your data call to get the geographic layer’s geometry along with your data.

Let’s map our data!

library(ggplot2)

plot <- ggplot(ease_of_access) +
  geom_sf(aes(fill = value), alpha = 0.7) +
  scale_fill_distiller(palette = "GnBu", direction = 1) +
  labs(
    title = "Easy Access to Fruits and Vegetables within Chicago",
    fill = "Percent of adults who reported\nthat it is very easy for them to\nget fresh fruits and vegetables."
  ) +
  theme_minimal()
plot

Our map looks pretty good, but perhaps there is a point layer that may provide more insight into the spatial variation of the ease of access to fruits and vegetables. We can use ha_point_layers() to list all the point layers available in the Chicago Health Atlas.

point_layers <- ha_point_layers()

Grocery store locations may be an important aspect of the ease of access to fruits and vegetables. We can import this layer by providing the point_layer_uuid to ha_point_layer().

grocery_stores <- ha_point_layer("7d9caf3c-75e6-4382-8c97-069696a3efbf")

Now that we have imported our grocery stores, let’s layer them on top of our map.

plot +
  geom_sf(data = grocery_stores, size = 0.5)

As expected, it seems that the areas with more grocery stores tend to have a higher percent of adults who report that it is very easy to get fresh fruits and vegetables.

This is a typical use case for the healthatlas in which we explored every function that healthatlas has to offer. Now it’s time for you to explore!
