Dear R-users, When I tried to import a text file (tab delimited) which has 2000+ rows with the following command (With the importData in S, it works though), x <- read.table(textfile, sep= "\t", skip=5, stringAsFactors=F) I received the following warning message: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,: number of items read is not a multiple of

Hi, Sorry if this may be a simple question. Is there any function to calculate returns (percentage or non-percentage) directly like the function getReturns() in S Finmetrics? Thanks.

Hi, I'm trying to use read.fwf temp = read.fwf ("Raw data.txt", widths = c (11, 21, 10, rep (16, 6)) ,skip = 2, n = 2, stringsAsFactors = FALSE, strip.white = TRUE) but no matter what I do the strings are turned into factors. I believe it's the "n=2" parameter that causes the problem as it seems to work without this. Am I missing something? Thanks in advance,

Hi I'm having a problem using the zoo library and I can't see what I'm doing wrong. For example setting up the data > t1 = zoo (matrix (1:12, nrow = 3), order.by = as.Date (c("2008-08-01","2008-08-02","2008-08-03"))) > colnames (t1) = c ("A", "B", "C", "D") > t2 = zoo (matrix (1:12, nrow = 3), order.by =

Gabor As someone trying to the rest of my team using Subversion (which I have used for a while, but more as a backup / record of changes), have you a neat / automated way of building a package from a subversion repository?

I suspect there is a simple solution to this problem, but have been unable to find it. Below is some code that I have run to create 3 lattice graphs. I have been asked to change the legend so that the 'No' and dark blue are above "Y" and light blue in the legend to mirror the stacked bars in the graph which feature dark blue above light blue. I have tried changing the data

Hi, I want to call R from within Java, using jri as per http://www.rosuda.org/software/jri/ So I am following the instructions in the README file for JRI 0.2-4. I have run 'sh configure.win' and 'make' and they seemed to be successful. (See below for the output from make, for example.) But when I try 'run.bat rtest' (with and without R command line arguments) the output

Hi All, I've been fiddling around with various ways to estimate the popularity of R, SAS, SPSS, Stata, JMP, Minitab, Statistica, Systat, BMDP, S-PLUS, R-PLUS and Revolution R. It's not an easy task. You can see what I've come up with so far at http://r4stats.com/popularity . I'm sure people will have plenty of ideas on how to improve this, so please let me know what you think.

Hi all, I have two questions. Can some one give some help? The first question is regarding the pair of operators "&" and "&&". What is the difference between the two? The second question is regarding "<-" and "=". Usually we use "<-" as the assignment operator. I saw some people use "=". Is there any

Dear R-list I am (forced) to change from Linux to Mac and am now looking for a new editor for R. I would like one that features a split window (console + editor) as well as syntax highlighting. Can anyone help? Especially the split-window feature does not seem to be easily available in the editors desribed on the R-help site, except Emacs, which I am reluctant to start using. I am on a MacBook Air

Hi, Using the Rconsole file I can specify the size and location of the Rgui windows on NT. e.g. # Dimensions (in characters) of the console. rows = 51 columns = 100 How can I specify the size of the help windows that popups when I ask for help? e.g. '?help' I would like the popup window to have say rows = 51 and columns = 100, just like the main window but a different location on the

Hi all Does anyone know if it is possible when plotting a line or scatter plot, to selectively color the data points based on the data value? i.e. if plotting say the percentage change in stock price movements, to color +ve points in green and -ve points in red? And extending this to a user-defined range of colors based on the quartile of the data points? Thanks Rory Rory Winston RBS Global

I'm kind of at a loss to diagnose problems like this, yet we get them a lot. - The ATA (Thomson 784 in this particular case) is logged into the Asterisk server. 'sip show peer' shows their IP address, port, and useragent. - The ATA is connected directly to the internet (no NAT, but the sip configuration has nat=always) and logs in to our server, which is also directly connected to the

Hello all, I am trying to implement a feature in my app where a user posts a message along with an image. This is something similar to what is there in `www.diasp.org` . I dealing with a pretty much outdated configuration of Rails 2.0.2 and Ruby 1.8.7 , both running on Ubuntu 10.04 OS for project specific purposes. Initially, I found a problem in finding an appropriate plugin for paperclip

I currently have a child class of a parent one. The parent defines some variable that I need to use in the child class. I am also using gepetto. Gepetto is complaining about the syntax of the child variable. It is saying that "$parentVar" should be "$::parentVar" however, when changing to what Gepetto wants to use this breaks my classes. Does anyone know the proper

Working from the help files and Bill Venables' R-news article (June 2002), I have tried various permutations with substitute without success. e.g. do.call("substitute", list(fun, list(a = as.name("x"), b = as.name("y")))) Regards, John.
