i.prices: Requests market data history (OHLC, volumes, dividends, etc.)
In ksavin/intrinio: API wrapper for intrinio.com financial data feeds.

1	i.prices(tickers, from = NULL, to = NULL, freq = "daily", ...)

`tickers`	tickers A character vector of stock symbols. For non-US tickers it is possible to specify exchange after tick symbol, separated by colon, i.e. "TICKER:EXCHANGE"
`from`	History start date (either Date or a character in 'YYYY-MM-DD' format), If `NULL`, date would not be restricted by a minimum. A vector of dates of the same length as tickers is also possible in order to have specific start date for each ticker.
`to`	History end date (either Date or a character in 'YYYY-MM-DD' format), If `NULL`, date would not be restricted by a maximum. A vector of dates of the same length as tickers is also possible in order to have specific end date for each ticker.
`freq`	Data periodicity. A string containing any of `'daily', 'weekly', 'monthly', 'quarterly', 'yearly'` or `NULL`. `NULL` will preserve default intrinio behavior (daily).
