quantmod

I am wondering how I can change date format. The code I am working on is following: library(quantmod) getSymbols("AAPL") price_AAPL <- AAPL[,6] plot(price_AAPL, main = "The price of AAPL") This results I want to alter date format from "%m %d %Y" as shown in the graphic to "%b-%d-%Y" So I tried following after searching some tips: plot(price_AAPL, main = "The price of AAPL", xaxt="n") axis.Date(1, at=seq(head(index(price_AAPL),1), tail(index(price_AAPL),1), length.out=5), format="%b-%d-%Y", las=2) But this doesn't help, and doesn't even show any labeling on x-axis. I suppose that I might did

I'm getting the same error in both quantmod and tinyquant for financials data. Can anyone see if this is reproducable? Is this a google finance server issue? None of the below functions have been working for me.I'm not sure if it's me or the server. tq_get("AAPL", get= "financials") [1] NA Warning message: x = 'AAPL', get = 'financials': Error in thead[x]:thead[x + 1]: NA/NaN argument and: getFin("AAPL") Error in thead[x]:thead[x + 1] : NA/NaN argument Can somebody help? Yes I get the same issue for the past couple of days as well. I think it may have to do with a change on the part of Google

I am using new chart_Series and add_TA quite a lot. It works very well for me and I find it very useful. I am trying to add a few things (horizontal lines and some text) on a graph. Here problems start to occur. After horizontal lines and text are drawn correctly they disappear if I call subsequent add_TA ... Please see the example code below which reproduces the problem: library(quantmod) getSymbols("SPY") dev.new() chart_Series(SPY) add_TA(ADX(HLC(SPY))$ADX) abline(h=15, col="red") abline(h=35, col="green") text(10, 7, "Text and horizontal lines disappear after next add_TA is called", col=

I'm currently downloading stock data using GetSymbols from the Quantmod package and calculating the daily stock returns, and then combining the data into a dataframe. I would like to do this for a very large set of stock symbols. See example below. In stead of doing this manually I would like to use a For Loop if possible or maybe use one of the apply functions, however I can not find the solution. This is what I currently do: Symbols<-c ("XOM","MSFT","JNJ","GE","CVX","WFC","PG","JPM","VZ","PFE","T","IBM","MRK","BAC","DIS","ORCL","PM","INTC","SLB") length(Symbols) #daily returns for selected

I am trying to pull some data in from the internet and then export it to a CSV file, but I am loosing my date information in the CSV file. I can't figure out why. I'm new to R so please keep responses simple. Here is my code: Library(quantmod) getSymbols("SPY", from = "2012-01-01", to = "2012-12-31") write.csv(SPY, "C:/SPY.csv") as SPY is a xts/zoo object this will do the trick: replace: write.csv(SPY, "C:/SPY.csv") with write.zoo(SPY,"C:/SPY.csv",index.name="Date",sep=",") DariusS Try: write.csv(SPY, file= "SPY.csv", row.names = index(SPY)) Are you sure that the date information is being lost

I'd like to do a vertical histogram. Ideally I should be able to put multiple on a single plot per day. If this could be combined with quantmod experimental chart_Series or some other library capable of drawing bars for a time series that would be great. Please see the attached screenshot. Ideally I could plot something like this. Is there anything built in or existing libraries that can help with this? I wrote something a year or so ago to do vertical histograms in base graphics. Here it is, with a usage example. VerticalHist <- function(x, xscale = NULL, xwidth, hist, fillCol = "gray80",

This is an advanced question. I use my own layout for the chartSeries quantmod function, and I can even create my own newTA. Everything works fine. But ... What I want to do but I can't: a) Manipulate the legend of each of the 3 charts: - move to other corner, (from "topleft" to "topright") - change the content - remove completely if needed ... b) My indicator generates 2 legends: value1 value2 same as above ... how could I modify them? how could I delete them? c) control position and range of yaxis (place it on the left / right or even remove them same when there is a secundary axis on the
