[R] CandlestickCharts of any listed stock and fetching stock prices into R

[Jim Lemon]

Hi Winod,
Your first error message seems to be saying that you are passing a
function that returns an "ohic" object rather than the object. Maybe:

ohic<-get.ohlc.yahoo("GOOG",start="2020-12-18",end="2021-12-17")
candlestickChart(ohic,..)

would get you a bit further. Also it's obvious that the function wants
character dates with quotes around them. There seem to be quite a few
YouTube tutorials on candlestick charts.
