Re withAutoprint(), Splus's source() function could take a expression (literal or not) in place of a file name or text so it could support withAutoprint-like functionality in its GUI. E.g., > source(auto.print=TRUE, exprs.literal= { x <- 3:7 ; sum(x) ; y <- log(x) ; x - 100}, prompt="--> ") --> x <- 3:7 --> sum(x) [1] 25 --> y <- log(x) --> x - 100 [1]

Martin, did you post your code for withAutoprint() anywhere? Building withAutoprint() on top of source() definitely makes sense, unless, as Bill says, source() itself could provide the same feature. To differentiate between withAutoprint({ x <- 1 }) and withAutoprint(expr) where is an expression / language object, one could have an optional argument `substitute=TRUE`, e.g. withAutoprint

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(*,

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

Hi All! I am interested in testing whether the means for the data I am investigating are equal to a specific value - let's say 0.01. I have already run a one-way ANOVA and know that the differences in the means are not significant, so now I want to know what values the means take on. "otestme" is the data I am working with (it would be hard for me to get into a form that would be

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

Dear R Helpers, I am still having trouble with the getOptionChain command in quantmod. I have the latest version of quantmod, etc. so I was under the impression that the problem was solved with updates to the package. If someone could let me know what I need to install in order to make this work, I would really appreciate it. My error message as session info are shown below. Thanks a bunch.

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

Dear R Helpers, I have run into a problem trying to perform a number of actions on a set of quantmod data objects through a loop and I am hoping that this is an easy problem for someone else as opposed to very difficult for me. The example task is to get the first three objects of the quarterly balance sheet for a number of companies from the getFinancials object and put them together into a

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 have a share with approximately 5000 folders in the base directory. The performance on an OS X client is somewhat less than exciting. I compiled the latest Samba 4.3 tarball and enabled fruit per the modules man 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
