Subset of daily COVID-19 doctor visits and cases from 6 states in archive format

Source: R/epiprocess-data.R
archive_cases_dv_subset.Rd

This data source is based on information about outpatient visits, provided to us by health system partners, and also contains confirmed COVID-19 cases based on reports made available by the Center for Systems Science and Engineering at Johns Hopkins University. This example data ranges from June 1, 2020 to December 1, 2021, issued on dates from June 1, 2020 to December 1, 2021. It is limited to California, Florida, Texas, and New York.

It is used in the epiprocess compactify, epi_archive, and advanced-use (advanced) vignettes.

Usage

archive_cases_dv_subset

Format

An epiprocess::epi_archive. The DT attribute contains the data formatted as a data.table::data.table (object of class c("data.table", "data.frame")) with 129638 rows and 5 columns.

Modifications:

  • From the COVIDcast Epidata API: case_rate_7d_av signal was computed by Delphi from the original JHU-CSSE data by calculating moving averages of the preceding 7 days, so the signal for June 7 is the average of the underlying data for June 1 through 7, inclusive.

  • Furthermore, the data has been limited to a very small number of rows, the signal names slightly altered, and formatted into an epi_archive.

Modifications:

  • From the COVIDcast Doctor Visits signal: The signal smoothed_adj_cli is taken directly from the API without changes.

  • Furthermore, the data has been limited to a very small number of rows, the signal names slightly altered, and formatted into an epi_archive.
