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

[R] CandlestickCharts of any listed stock and fetching stock prices into R
Hello,
R users community,
I want to plot candlestickCharts of any stock prices of listed companies
on any stock exchange (Indian or worldwide) into r by using
candlestickchart command in 'FinCal' r package. But I could not plot
candlestic charts. R showed me errors.
candlestickChart(ohlc,2020-12-18,2021-12-17,"Google")
Error in as.Date(ohlc$date) : object 'ohlc' not found
> candlestickChart(get.ohlc.google,2020-12-18,2021-12-17,"Google")
Error: object of type 'closure' is not subsettable
> candlestickChart(get.ohlc.google,2020-12-18,2021-12-17,"Google")
Error: object of type 'closure' is not subsettable
What is the suitable syntax to use candlestickchart command from 'FinCal' r
package?
I also tried to fetch stock prices of listed companies on any stock
exchange (wordwide or Indian) But I could not fetch stock prices.
# google <- get.ohlc.yahoo("GOOG",start="2014-07-01",end="2014-08-01");
candlestickChart(google)

How can I plot candlestickchart and fetch stock prices of any period with
any frequency of time intervals?

Re: [R] nlme::lme sigma parameter standard deviation or variance?
Modifying the first example in help('lme', pac='nlme'):
library(nlme)
fm1 <- lme(distance ~ age, data = Orthodont) # random is ~ age
fm1$sigma
fm1.2 <- lme(2*distance ~ age, data = Orthodont) # random is ~ age
fm1.2$sigma
Conclusion: Standard deviation, as indicated in help('lmeObject').
Hope this helps.

If this changes the result lme_mod$sigma by a factor of 2, then it is
a std deviation.
If it changes the result by a factor of 4, then it is a variance.

I am wondering whether lme_mod$sigma is actually a standard deviation or if

[R] problem with RSelenium....
dear members, I am using RSelenium. I have downloaded the java binary standalone server.
