similar to: TTR getYahooData?

Dear all, I'm totally new to R. Recently I've been trying to use getYahooData in TTR package in order to download stock index daily open/high/low/close. The downloaded data is in the format of Open High Low Close Volume 2000-01-04 18937.45 19187.61 18937.45 19002.86 0 2000-01-05 19003.51 19003.51 18221.82 18542.55 0 2000-01-06

library(xts) library(TTR) ndx = getYahooData("^NDX") aa = ndx$Close bb = aggregate(aa, as.yearweek, tail, 1) The last operation takes forever, and then the bb dates are messed up. The following produces the desired result: time(aa) = as.Date(time(aa)) bb = aggregate(aa, as.yearweek, tail, 1) The index of ndx and aa is of POSIXct (as reported by is(time(ndx))) , which apparently

I am using getYahooData from TTR to get daily data. When i do it standalone, it is fine. It also works fine inside my code. However, when i run code inside mtrace(), i always get the following error: Error in xts(cbind(adj[[1]], adj[[2]]), index(obj)): order.by requires an appropriate time-based object After a lot of hand wringing, it looks to me that it happens because index in xts masks

Hi Everyone, I'm currently using the latest build of R and R-Studio server (both are amazing products) I'm still very new to this but I came across this issue: I'm trying to do a select from postgres and put the data into and xts object like so: # Libs library('RPostgreSQL') # http://code.google.com/p/rpostgresql/ library('quantmod') library('TTR')

Hi, Just wondering for the SMA and EMA in package TTR, is it possible to me to code it so that, say if I need to calculate SMA (x, n=100), when the sample size is less than 100, it will give me the SMA (x, k) where k is the sample size of the data? Right now it only gives me an invalid n error. Thanks! [[alternative HTML version deleted]]

Dear expeRts, I would like to download a time series of historical data from the ticker with symbol "ROG.VX". Interestingly, I obtain constant values (138.3 for each day in the chosen period) although the yahoo.finance website tells me that the time series is not at all constant. What's wrong? Cheers, Marius require(tseries) hq <- get.hist.quote(instrument="ROG.VX",
