phsopendata

phsopendata contains functions to interact with open data from the Scottish Health and Social Care Open Data platform via the CKAN API.

• get_resource() extracts a single resource from an open dataset by resource id
• get_latest_resource() extracts the most recent resource from applicable datasets, by dataset name
• get_dataset() extracts multiple resources from an open dataset by dataset name
• list_datasets() returns the names of all available datasets
• list_resources() returns information on all resources within an open dataset by dataset name

phsopendata can be used on both Posit Workbench and desktop versions of RStudio.

Installation

# The easiest way to get phsopendata is to install from CRAN:
install.packages("phsopendata")

Development version

To get a bug fix or to use a feature from the development version, you can install the development version of phsopendata from GitHub.

# install.packages("remotes")
remotes::install_github("Public-Health-Scotland/phsopendata")

Examples

Downloading a data table with get_resource()

To extract a specific resource, you will need its unique identifier - resource id. This can be found in the dataset metadata, the URL of a resource’s page on https://www.opendata.nhs.scot/, or extracted using list_resources().

library(phsopendata)

# define a resource ID
res_id <- "a794d603-95ab-4309-8c92-b48970478c14"

# download the data from the CKAN database
data <- get_resource(res_id = "a794d603-95ab-4309-8c92-b48970478c14")

Querying/filtering data with get_resource()

You can define a row limit with the rows argument to get the first N rows of a table.

# get first 100 rows
get_resource(
  res_id = "a794d603-95ab-4309-8c92-b48970478c14",
  rows = 100
)

You can use col_select and row_filters to query the data server-side (i.e., the data is filtered before it is downloaded to your machine).

# get first 100 rows
get_resource(
  res_id = "a794d603-95ab-4309-8c92-b48970478c14",
  col_select = c("GPPracticeName", "TelephoneNumber"),
  row_filters = list(
    HB = "S08000017",
    Dispensing = "Y"
  )
)

Downloading multiple tables with get_dataset()

To extract all resources from a dataset, you will need to use the dataset name. Note that this will differ from the dataset title that displays on the website. This can be found using list_datasets(), or taken from the dataset URL.

In this example, we are downloading GP Practice Population Demographics from: opendata.nhs.scot/dataset/gp-practice-populations, so the dataset name will be gp-practice-populations.

# if max_resources is not set, all resources will be returned by default.
# Here we pull 10 rows from the first 2 resources only
get_dataset("gp-practice-populations", max_resources = 2, rows = 10)
