I'm trying to install the rdatamarket package. I did an install.packages('rdatamarket') command but got an error about half way through the install as follows: * installing *source* package ?RCurl? ... checking for curl-config... no Cannot find curl-config ERROR: configuration failed for package ?RCurl? The install continued after the error but looks like it was completed. I'm

Using the rmarketdata package and getting a warning message. What does this warning message tell me ? What could I do to eliminate or address it ? require(rdatamarket) Loading required package: rdatamarket Loading required package: zoo Warning message: In assignInNamespace("as.Date.numeric", function(x, origin, ...) { : binding of ?as.Date.numeric? is locked and will not be

Hi, I'm having trouble with quantmod's addTA plotting functions. They seem to work fine when run from the command line. But when run inside a function, only the last one run is visible. Here's an example. test.addTA <- function(from = "2010-06-01") { getSymbols("^GSPC", from = from) GSPC.close <- GSPC[,"GSPC.Close"] GSPC.EMA.3

Hi there, Using a quantmod function, I calculate the daily change between two points in a time series. However, I don't think I am using the data correctly. Code: getSymbols("^GSPC", src="yahoo") CloseData <- Cl(GSPC) Delta <- diff(CloseData, lag=1) for (i in 3:length(Delta)) { if (Delta[i]>Delta[i-1]) sum <- sum + Delta } I can't seem to use the Delta

I have the following simple for-loop, which makes R crash every time. The length of the vectors is about 1200 rows, 1 column. n = max(length(GSPC),length(FTSE)) for(i in 1:1000) { if (row.names(GSPC)[i]==row.names(FTSE)[i]){ } else { if (row.names(GSPC)[i]>row.names(FTSE)[i]){ GSPC<-rbind(GSPC[1:(i-1),],GSPC[(i-1):length(GSPC),]) row.names(GSPC)[i]=row.names(FTSE)[i] } else {

I'm calling a list of symbols and then using a function to build a data frame from that symbol list. It works great until I introduce this index symbol from yahoo '^GSPC'. When and index symbol is introduced I get and error which is below. > Data <- symbolFrame(symbols) Error in get(S) : object '^GSPC' not found Since R does not like the ^ in front of a name it

Thanks, Writing plot(addTA()) worked fine. I find myself with such mixed feelings about R. After finding that addTA worked fine at the command line but not in a function, I puzzled for a long time about what kind of virtual machine structure could possibly account for that. I couldn't think of any. It turns out that this isn't due to an R virtual machine structure. The reason addTA adds

I have the following lines of code: ind <- rollapply(GSPC, 200, mean) signal <- ifelse(diff(ind, 5) > 0 , 1 , -1) signal[is.na(signal)] <- 0 I never get a value of -1 for signal even though I know diff(ind , 5) is less than zero frequently. It looks like when diff(ind , 5) is less than zero, signal gets set to 0 instead of - 1. Any ideas why ? Here's some information on ind and

Hi, I am trying to add a rectangular colored background area to a plot of a time series of relative price changes. I believe that what I'm trying to do is very similar to the question and example given here: http://www.mail-archive.com/r-help at stat.math.ethz.ch/msg73948.html http://www.mayin.org/ajayshah/KB/R/html/g5.html My problem/difference is that my time series looks like so: >

Hello, I am trying to write a tcltk based program that plots/manipulates xts/xoo time series objects. I have the code I used from ## http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tkrplot.html : ## require(quantmod) require(tcltk) library(tkrplot) Sys.setenv(TZ="GMT") getSymbols("^GSPC", from = "1960-01-01") Myhscale <- 2.5 # Horizontal scaling

Hello, I have problem with using color. plot(data_min1$macd,col='black',main="1 min MACD",type="l") lines(data_min1$macdsig,col="red") par(new=T) plot(data_min1$macdhist,col=data_min3$histcol,type="h",main="") axis(4,col='black') par(new=F) When I remove ",col=data_min3$histcol" in the 2nd plot()

Hi R users,   Thanks in advance.   I am using R 2.12.0 on Windows XP.   May I request you to assist me in the following please.   1. I am getting error while downloading quote data from yahoo finance.   The example code is below (taken from tseries help):   library(tseries)   con <- url("http://quote.yahoo.com") if(!inherits(try(open(con), silent = TRUE), "try-error")) {  

Hello This is my first post on this forum and I hope someone can help me out. I have a datafile (weeklyR) with returns of +- 100 companies. I acquired this computing the following code: library("tseries"); tickers = c("GSPC" , "BP" , "TOT" , "ENI.MI" , "VOW.BE" , "CS.PA" , "DAI.DE" , "ALV.DE" ,

I found an example at http://www.bearcave.com/finance/random_r_hacks/kalman_smooth.html shown below. But it seems the structSSM function has been removed from KFAS library so it won't run. Does anyone know how to fix the code so that it runs? library(KFAS) library(tseries) library(timeSeries) library(zoo) library(quantmod) getDailyPrices = function( tickerSym, startDate, endDate ) {

Hello, I have a few questions concerning the DCC-GARCH model and its programming in R. So here is what I want to do: I take quotes of two indices - S&P500 and DJ. And the aim is to estimate coefficients of the DCC-GARCH model for them. This is how I do it: library(tseries) p1 = get.hist.quote(instrument = "^gspc",start = "2005-01-07",end =

Dear list members, How can I shade the background area of a zoo time series object between specific dates? eg. library(tseries) library(zoo) SP500<-get.hist.quote("^GSPC", start = "1990-01-01", quote = "Close") plot(SP500) How can I produce the same plot but with a (say) red background between 2007-04-12 and 2008-05-14 ?

Hello, I have a rather complex problem... I will have to explain everything in detail because I cannot solve it by myself...i just ran out of ideas.

Hi, I have been using R for over a year now. I am a very happy user. Thank you for making this happen. This is my first question to this list. I trying to add some functions to quantmod that would enable me to draw arbitrary lines and text and make sure they are redrawn. I have created following function: require(quantmod) # Add horizontal line to graph produced by quantmod::chart_Series()

> structSSM Is no longer part of KFAS. All you needed to do was: library(KFAS) ?KFAS and you would have seen that if you went to the index. A structural state space model is now built up from its components, much like in LM.
