API docs: https://cmu-delphi.github.io/delphi-epidata/api/covidcast_signals.html
The primary endpoint for fetching COVID-19 data, providing access to a wide variety of signals from a wide variety of sources. See the API documentation link above for more. Delphi's COVIDcast public dashboard is powered by this endpoint.
Usage
pub_covidcast(
source,
signals,
geo_type,
time_type,
geo_values = "*",
time_values = "*",
...,
as_of = NULL,
issues = NULL,
lag = NULL,
fetch_args = fetch_args_list()
)
Arguments
- source
string. The data source to query (see: https://cmu-delphi.github.io/delphi-epidata/api/covidcast_signals.html).
- signals
string. The signals to query from a specific source (see: https://cmu-delphi.github.io/delphi-epidata/api/covidcast_signals.html).
- geo_type
string. The geographic resolution of the data (see: https://cmu-delphi.github.io/delphi-epidata/api/covidcast_geography.html).
- time_type
string. The temporal resolution of the data (either "day" or "week", depending on signal).
- geo_values
character. The geographies to return. Defaults to all ("*") geographies within requested geographic resolution (see: https://cmu-delphi.github.io/delphi-epidata/api/covidcast_geography.html.).
- time_values
timeset
. Dates to fetch. Defaults to all ("*") dates.- ...
not used for values, forces later arguments to bind by name
- as_of
Date. Optionally, the as of date for the issues to fetch. If not specified, the most recent data is returned. Mutually exclusive with
issues
orlag
.- issues
timeset
. Optionally, the issue of the data to fetch. If not specified, the most recent issue is returned. Mutually exclusive withas_of
orlag
.- lag
integer. Optionally, the lag of the issues to fetch. If not set, the most recent issue is returned. Mutually exclusive with
as_of
orissues
.- fetch_args
fetch_args
. Additional arguments to pass tofetch()
.
