Returns

nhs data.frame of nhs regions

Method add_nhs_regions()

Add NHS data for level 1 regions Separate NHS data is available for "first" admissions, excluding readmissions. This is available for England + English regions only. See: https://www.england.nhs.uk/statistics/statistical-work-areas/covid-19-hospital-activity/ Section 2, "2. Estimated new hospital cases"

Method specific_tests()

Specific tests for UK data. In addition to generic tests ran by DataClass$test() data for NHS regions are downloaded and ran through the same generic checks (test_cleaning, test_processing, test_return). If download = TRUE or a snapshot file is not found, the nhs data is downloaded and saved to the snapshot location provided. If an existing snapshot file is found then this data is used in the next tests. Tests data can be downloaded, cleaned, processed and returned. Designed to be ran from test and not ran directly.

Usage

UK$specific_tests(
  self_copy,
  download = FALSE,
  all = FALSE,
  snapshot_path = "",
  ...
)

Arguments

self_copy

R6class the object to test.

download

logical. To download the data (TRUE) or use a snapshot (FALSE). Defaults to FALSE.

all

logical. Run tests with all settings (TRUE) or with those defined in the current class instance (FALSE). Defaults to FALSE.

snapshot_path

character_array the path to save the downloaded snapshot to. Works on the snapshot path constructed by test but adds

...

Additional parameters to pass to specific_tests

Method clone()

Usage

UK$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

if (FALSE) {
# setup a data cache
start_using_memoise()

# download, clean and process level 1 UK data with hospital admissions
region <- UK$new(level = "1", nhsregions = TRUE)
region$return()

# initialise level 2 data
utla <- UK$new(level = "2")

# download UTLA data
utla$download()

# clean UTLA data
utla$clean()

# inspect available level 1 regions
utla$available_regions(level = "1")

# filter data to the East of England
utla$filter("East of England")

# process UTLA data
utla$process()

# return processed and filtered data
utla$return()

# inspect all data steps
