)(character) A (single or vector) symbol understood by the backend as a stock symbol, foreign exchange pair, or more. See the ‘twelvedata’ documentation for details on what is covered. In the case of a vector of arguments a list is returned.
(character) A valid interval designator ranging form “1min” to “1month”. Currently supported are 1, 5, 15, 30 and 45 minutes, 1, 2, 4 hours (using suffix ‘h’, as well as “1day”, “1week” and “1month”.
(optional, character) A selector for the desired output format: one of “data.frame” (the default) or or “raw”.
(optional, character) A selection of the exchange for which data for “sym” is requested, default value is unset.
(optional, character) The timezone of the returned time stamp. This parameter
is optional. Possible values are “Exchange” (the default) to return the
exchange-supplied value, “UTC” to use UTC, or a value IANA timezone name such as
“America/New_York” (see link{OlsonNames} to see the values R knows). Note
that the IANA timezone values are case-sensitive. Note that intra-day data is converted to
an R datetime object (the standard POSIXct type) using the exchange timestamp in
the returned metadata, if present.
(optional character) An API key override, if missing a value cached from
package startup is used. The startup looks for either a file in the per-package config
directory provided by tools::R_user_dir (for R 4.0.0 or later), or the
TWELVEDATA_API_KEY variable.
The requested data is returned as a data.frame object.
