Hi, I was wondering what is the recommended way to install the "vars" package in debian. And for that matter, how do you usually install R packages not included in debian? I guess I could simply use install.packages() but I'm afraid of ending up with several versions of the same package which could be bad I guess... Any recommendation on how to go with this? Thanks in advance for

Running linux 10.04 ubuntu. Looks like Ubuntu automatically updated to version 2.13. I was running version 2.12 until today. But now I'm getting error messages when I use the require or library command and one of the packages I've downloaded in the past. For example: > require(quantmod) Loading required package: quantmod Warning message: In library(package, lib.loc = lib.loc,

Hi, I've been using r (the little, but sweet one!), and recently found out about the magic argv vector of the rest of arguments passed to it. How can we process an argument that represents elements of a vector: $ r littler_ex.R 14 '3, 2' Error in ff * ss : non-numeric argument to binary operator where: ,-----[ cat ~/scripts/R/littler_ex.R ] | ff <- as.numeric(argv[1]) | ss

Hello, I want to add some new functionalities in the package 'quantmod '. So I download source code and am managed to build it. I found that modifying code and check if it works by repeating the following steps: 1) r CMD check quantmod 2) r CMD build quantmod 3) r CMD INSTALL quantmod_0.3-17.tar.gz 4) launch R gui 5) library('quantmod') 6) run my script Let me know if there

After some frustrations with installing some R packages from source, usually related to library dependencies or suspected kernel problems (recent one with Ubuntu and Rmpi) I decided to give Debian a try. I'm working through the tutorial found at http://cran.r-project.org/bin/linux/debian/ and I have a couple questions about how packages are best updated between releases of R. Many R packages

Hi all, I would appreciate some help in understanding how to find out about objects. For example, to the extent that I understand R it seems to treat everything as an object even without declaring them as objects. Everything has attributes, for example, which are like instance variables in objects. In addition, there are S3 and S3 category objects. Is there a good introductory description of how

Hello, I apologize that I am cross posting here after getting no answer from my initial question on stack overflow <http://stackoverflow.com/questions/33492601/r-setoldclass-only-if-needed>. I should certainly have posted it first here.. I am using 3 packages: - xts - quantmod - 'myPackage' quantmod is creating a union class by doing: setOldClass("xts");

Hi, I am using two packages (quantmod and FRAPO) Quantmod and FRAPO both have a class names "zoo" R is displaying the following warning when I manipulate an object of class zoo: Found more than one class "zoo" in cache; using the first, from namespace 'quantmod' Also defined by ?FRAPO? The warning is displayed every time I manipulate a zoo object and becomes pretty

Hi, I'm new to R and Quantmod. I'm trying to make use of Quantmod's features however I'm failing at the first hurdle and I'm finding most R documentation a little cryptic. I have some minutely data for the same day for a stock in an existing timeSeries (ts) object. For example: Date time price volume 2012-03-12 08:01 45.01 10000 2012-03-12 08:02

Hi. I would like to know how to start an embedded R session, and avoid datasets and the standard library packages to be loaded on startup. I've been looking at littler's code (so this is partly a question to Dirk Eddelbuettel...): > /* We don't require() default packages upon startup; rather, we > * set up delayedAssign's instead. see autoloads(). >

i am new to the quantmod package . so if the answer is trivial please excuse me. i want to study stock values within a day. i get current stock updates using getQuotes and then want to produce usual quantmod graphs with that values. also the graph should be able of adding technical indicators. please help. in addition it will be helpful if anyone suggests how to run that code continuously to get

Hi all, I would need to put datas downloaded with quantmod into a matrix or a data frame. Suppose to start from here: *require(quantmod) ticker.list <- c('AAA', 'ALTSALES', 'AMBNS', 'AMBSL', 'BAA', 'EMRATIO', 'FEDFUNDS', 'GASPRICE', 'GS1', 'GS10', 'GS20', 'LNS14100000', 'MORTG',

Hi Charlie, I am comfortable to put the data in any way that works best. Here are two possibilities: an xts and a data frame. library(quantmod) quantmod::getSymbols("SPY") # creates xts variable SPY SPYxts <- SPY[,c("SPY.Close","SPY.Volume")] SPYdf <- data.frame(Date=index(SPYxts),close=as.numeric(SPYxts$SPY.Close),

Hello, I'm trying to do two things: -1. Ensure that I understand how quantmod adjust's OHLC data -2. Determine how I ought to adjust my data. My overarching-goal is to adjust my OHLC data appropriately to minimize the difference between my backtest returns, and the returns I would get if I was trading for real (which I'll be doing shortly). Background: -1. I'm using Alpha

Yes, you need to cite the source of data and the method for retrieval. You also need to cite programs used in manipulating the data, cleaning the data, and analyzing the data. I should be able to read what you wrote, and using those methods recover the data independently from you and finish all other steps in the analysis. I should not have to guess.

OpCl works on xts objects but not on quantmod.OHLC objects. Is this a bug? Example error: x.Date <- as.Date("2003-02-01") + c(1, 3, 7, 9, 14) - 1 set.seed(1) x <- zoo(matrix(runif(20, 0, 1), nrow=5, ncol=4), x.Date) q <- as.quantmod.OHLC(x,c("Open","High","Low","Close")) # error OpCl(q) #> Error in `colnames<-`(`*tmp*`, value =
