`sym`	(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.
`interval`	(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”.
`as`	(optional, character) A selector for the desired output format: one of “data.frame” (the default) or or “raw”.
`exchange`	(optional, character) A selection of the exchange for which data for “sym” is requested, default value is unset.
`timezone`	(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.
`apikey`	(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.
