Interface to subnational and national level COVID-19 data sourced from both official sources, such as Public Health England in the UK, and from other COVID-19 data collections, including the World Health Organisation (WHO), European Centre for Disease Prevention and Control (ECDC), John Hopkins University (JHU), Google Open Data and others. This package is designed to streamline COVID-19 data extraction, cleaning, and processing from a range of data sources in an open and transparent way. This allows users to inspect and scrutinise the data, and tools used to process it, at every step. For all countries supported, data includes a daily time-series of cases and, wherever available, data on deaths, hospitalisations, and tests. National level data is also supported using a range of data sources as well as line list data and links to intervention data sets.

Load covidregionaldata, dplyr, scales, and ggplot2 (all used in
this quick start),
library(covidregionaldata)
library(dplyr)
library(ggplot2)
library(scales)This package can optionally use a data cache from memoise to locally
cache downloads. This can be enabled using the following (this will use
the temporary directory by default),
start_using_memoise()
#> Using a cache at: /tmp/RtmpPgZXivTo stop using memoise use,
stop_using_memoise()and to reset the cache (required to download new data),
reset_cache()To get worldwide time-series data by country (sourced from the World Health Organisation (WHO) by default but also optionally from the European Centre for Disease Control (ECDC), John Hopkins University, or the Google COVID-19 open data project), use:

g7 <- c(
"United States", "United Kingdom", "France", "Germany",
"Italy", "Canada", "Japan"
)
g7_nots <- get_national_data(countries = g7, verbose = FALSE)Using this data we can compare case information between countries, for example here is the number of deaths over time for each country in the G7:
g7_nots %>%
ggplot() +
aes(x = date, y = deaths_new, col = country) +
geom_line(alpha = 0.4) +
labs(x = "Date", y = "Reported Covid-19 deaths") +
scale_y_continuous(labels = comma) +
theme_minimal() +
theme(legend.position = "top") +
guides(col = guide_legend(title = "Country"))
To get time-series data for subnational regions of a specific country, for example by level 1 region in the UK, use:
uk_nots <- get_regional_data(country = "UK", verbose = FALSE)

uk_nots %>%
filter(!(region %in% "England")) %>%
ggplot() +
aes(x = date, y = cases_new, col = region) +
geom_line(alpha = 0.4) +
labs(x = "Date", y = "Reported Covid-19 cases") +

theme_minimal() +
theme(legend.position = "top") +
guides(col = guide_legend(title = "Region"))
See get_available_datasets() for supported regions and subregional
levels. To view what datasets we currently have subnationaldata for,
along with their current status, check the supported
countries
page or build the supported countries
vignette.
For further examples see the quick start
vignette.
Additional subnational data are supported via the JHU() and Google()
classes. Use the available_regions() method once these data have been
downloaded and cleaned (see their examples) for subnational data they
internally support.
