Used to specify custom options when making API requests, such as to set
timeouts or change data formats. These options are used by fetch() when it
makes calls to the Epidata API.
Usage
fetch_args_list(
...,
fields = NULL,
disable_date_parsing = FALSE,
disable_data_frame_parsing = FALSE,
return_empty = FALSE,
timeout_seconds = 15 * 60,
base_url = NULL,
dry_run = FALSE,
debug = FALSE,
format_type = c("json", "classic", "csv")
)Arguments
- ...
not used for values, forces later arguments to bind by name
- fields
a list of epidata fields to return, or
NULLto return all fields (default). e.g.c("time_value", "value")to return only thetime_valueandvaluefields orc("-direction")to return everything except the direction field- disable_date_parsing
disable automatic date parsing
- disable_data_frame_parsing
disable automatic conversion to data frame; this is only supported by endpoints that only support the 'classic' format (non-tabular)
- return_empty
boolean that allows returning an empty tibble if there is no data
- timeout_seconds
the maximum amount of time (in seconds) to wait for a response from the API server
- base_url
base URL to use; by default
NULL, which means the global base URL"https://api.delphi.cmu.edu/epidata/"- dry_run
if
TRUE, skip the call to the API and instead return theepidata_callobject (useful for debugging)- debug
if
TRUE, return the raw response from the API- format_type
the format to request from the API, one of classic, json, csv; this is only used by
fetch_debug, and by default is"json"
