covid19swiss

The covid19swiss R package provides a tidy format dataset of the 2019 Novel Coronavirus COVID-19 (2019-nCoV) pandemic outbreak in Switzerland cantons and the Principality of Liechtenstein (FL). The package is following the data structure of the Covid19R project.

The covid19swiss dataset includes the following fields:

  • date - the timestamp of the case, a Date object
  • location - the Cantons of Switzerland and the Principality of Liechtenstein (FL) abbreviation code
  • location_type - description of the location, either Canton of Switzerland or the Principality of echtenstein
  • location_code - a canton index code for merging geometry data from the rnaturalearth package, ailable only for Switzerland cantons
  • location_code_type - the name of code in the rnaturalearth package for Switzerland map
  • data_type - the type of case
  • value - the number of cases corresponding to the date and data_type fields

Where the available data_type field includes the following cases:

  • tested_total - cumulative number of tests performed as of the date
  • cases_total - cumulative confirmed Covid-19 cases as of the current date
  • hosp_new - new hospitalizations on the current date
  • hosp_current - current number of hospitalized patients as of the current date
  • icu_current - number of hospitalized patients in ICUs as of the current date
  • vent_current - number of hospitalized patients requiring ventilation as of the current date
  • recovered_total - cumulative number of patients recovered as of the current date
  • deaths_total - cumulative deaths due to Covid-19 as of the current date

Missing values

The data is collected from multiple resources on the canton level, and not necessarily each data resource provides the same field. Therefore, some fields, such as total recovered or total tested may not be available at this point for some cantons and are marked as missing values (i.e., NA).
