Description

This is a convenience function for exercises in the Data Computing book. It reads stock prices and dividends over a specified time interval.

Usage

read_stock_prices(symbols = "F", what = c("prices", "daily", "weekly",
  "monthly", "dividends"), start_year = 1972, end_year = 2015)

Arguments

symbols	a single character string or a vector of character strings specifying a stock listed on yahoo.finance.
what	whether to read prices or dividends. For prices, use one of "daily", "weekly", "monthly". For dividends, use "dividends".
start_year	the lower end of the time interval for which to download data
end_year	the upper end of the time interval

Details
