R access to SimFin share prices
What it is
An R package that wraps the SimFin web API so share prices can be loaded into data frames. A share-price call takes a list of tickers and returns dates, dividends, shares outstanding and open, high, low and closing prices, and every exported function shares one prefix. Analysts working in R who already hold a SimFin account can set the key and a cache directory once, then reuse cached responses across sessions. The package is marked experimental, and requests do not run until you register for an API key.
