Hi, I work with SEXP C code and with xts and quantmod packages. I try to touch how xts internal works. So we have R session and: > ls() character(0) > getSymbols('AAPL') # quantmod package [1] "AAPL" > ls() [1] "AAPL" > str(AAPL) An ?xts? object from 2007-01-03 to 2010-09-09 containing: Data: num [1:929, 1:6] 86.3 84 85.8 86 86.5 ... - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:6] "AAPL.Open"...

Dear Sir/Madam, How to use getSymbols() to get annual data? For example, I need the annual stock price of APPLE from the year 2000 to 2016. How to write the command? I only know how to get the daily data. It is: getSymbols("AAPL",from="2000-01-01",to="2016-12-31") Thank you very much. Have a good week!

I am using the getQuote function in the Quantmod package to retrieve the % change for a stock as follows: > getQuote("aapl",what=yahooQF(c("Change Percent (Real-time)"))) Trade Time %Change (RT) aapl 2012-10-11 03:41:00 N/A - -1.67% How can I extract the numeric "change %" which is being returned as a factor so that I can use it in other calculations? Thanks.

...n page, however directory listing performance still takes a few seconds. I've cranked the fruit debug level up to 10 and can see that it is getting used ("fruit_stat called for files", for instance). I've also looked through Wireshark and it appears to appropriately negotiate the AAPL extension with the client. In wireshark I'm still seeing a GetInfo Request for every file and directory which hammers my poor server. I was under the impression the aapl protocol extension was supposed to make these requests unnecessary. Am I misunderstanding the functionality or is something...

...atest Samba 4.3 tarball and enabled fruit per the modules man page, > however directory listing performance still takes a few seconds. sounds reasonable for 5000 elements in a folder. How long does it take without fruit? You may be able to squeeze some more out of it by adding: readdir_attr:aapl_max_access = false This results in the clients incorrect view of effective permissions though, but if everything is eg 0777 anyway than why care? > I've cranked the fruit debug level up to 10 and can see that it is getting > used ("fruit_stat called for files", for instance)....

Hello, all-- I am having some fun playing with the graphing in quantmod-- very nice! I am writing a function to calculate (and hopefully plot) support and resistance lines, but the usual plot call of "abline(h=value)" does not seem to work. Here's my code: require(quantmod) AAPL<-getYahooData("AAPL") candleChart(AAPL,subset="last 3 months",theme="white") addMACD() abline(h=290,col="red") The same sequence works fine if I'm just using a plain vanilla "plot" call, however. What am I missing? Do I need to call the li...

I'm sure there is a more general way to ask this question but how do you use the elements of a character vector as names of objects in an expression? For example, say you have: a = c(1,3,5,7) b = c(2,4,6,8) n=c("a","b") and you want to use the names a and b in a function (e.g. sum) sum(eval(as.name(n[1])),eval(as.name(n[2]))) works but what is a simpler way to

...If I download yahoo data by getSymbols() in R, the date column gets accompanied along with the downloaded data. There is no column header for the date column to access separately. What is the way to eliminate the date column? If I want to draw a xy scatter plot with the downloaded price (suppose AAPL vs NASDAQ), I think the date column is creating problem and the plot function is not working. Please advise on this as I am very new to R.
