Obtain COVIDcast metadata

Description

Obtains a data frame of metadata describing all publicly available data streams from the COVIDcast API.

Usage

covidcast_meta()

Value

Data frame containing one row per signal, with the following columns:

data_source	Data source name.
signal	Signal name.
min_time	First day for which this signal is available.
max_time	Most recent day for which this signal is available.
geo_type	Geographic level for which this signal is available, such as county, state, msa, or hrr. Most signals are available at multiple geographic levels and will hence be listed in multiple rows with their own metadata.
time_type	Temporal resolution at which this signal is reported. "day", for example, means the signal is reported daily.
num_locations	Number of distinct geographic locations available for this signal. For example, if geo_type is county, the number of counties for which this signal has ever been reported.
min_value	Smallest value that has ever been reported.
max_value	Largest value that has ever been reported.
mean_value	Arithmetic mean of all reported values.
stdev_value	Sample standard deviation of all reported values.
max_issue	Most recent issue date for this signal.
min_lag	Smallest lag from observation to issue, in time_type units
max_lag	Largest lag from observation to issue, in time_type units
