covidsymptom: COVID Symptom Study-Sweden data

Description

Easily imports COVID Symptom Study-Sweden open data

Details

The COVID Symptom Study is a non-commercial project that uses a free smartphone app to facilitate real-time data collection of symptoms, exposures, and risk factors related to COVID-19. The app was developed by researchers at King’s College and Guys and St Thomas’ Hospitals in London in partnership with health science company Zoe Global Ltd. Baseline data and recurring daily questions are described in Drew et al (Science, 2020). The app was launched in the UK and US March 2020. In Sweden, the study is based at Lund University and, as per a collaboration agreement on 28 July 2020, Uppsala University. The app was launched in Sweden on April 29, 2020 as part of a national research initiative on COVID-19. To date, >4.5 million participants in the three countries are using the app, ~202,000 of whom live in Sweden. Participants have so far made ~271 million data entries, with Swedish participants contributing ~11 million of these.

Retrieve updated COVID Symptom Study Sweden (CSSS) data

Description

This function was originally designed to download the latest version of CSSS data dynamically. Due to the cessation of data updates from the COVID Symptom Study Sweden, this function now checks if locally stored data is up-to-date and notifies the user accordingly. The function will not fetch new data from online sources.

Usage

get_latest_data(data_level = c("national", "county", "postcode"))

Arguments

Details

Note: As the COVID Symptom Study Sweden is no longer updating their data sets, this function serves as a demonstration of how data updates could be managed without needing frequent package updates. It returns the data that was last available before updates were discontinued.

Value

This function returns a data.frame containing the data for the specified level. Data returned is the last available snapshot stored within the package.

Update COVID Symptom Study Sweden (CSSS) data

Description

Originally, this function would update the package datasets in the global environment with the most recent data from the development version of the package. However, as updates to the CSSS dataset have been discontinued, this function now simply notifies that no updates are available.

This function served to ensure that the package datasets remained up-to-date without requiring a full package reinstallation. It would compare the local version of the data with the latest online version and offer to update if newer data were found.

Due to the discontinuation of data updates from CSSS, this function now only serves to inform users that no new updates will be provided, preserving its structure for educational or demonstration purposes.

Usage

update_csss_data(silence = FALSE)

Arguments

Value

None. This function now simply prints a message to the console indicating that the function has been disabled and no updates are available.

Examples

update_csss_data() # This will print a message that no updates are available.
