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?

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

I am new in R. Can anyone tell : 1. how we can write our own functions in R ? 2. how we can save those functions and recall to use them? 3. what extensions are used for saving a file? -- Siddharth Arun, 4th Year Undergraduate student Industrial Engineering and Management, IIT Kharagpur [[alternative HTML version deleted]]

Dear readers, There is a combination of keys that I have (on several occasions now) typed by accident into R (2.10.0) which removes all the objects in the environment, and clears the console, as though I had typed rm(list=ls()). Unfortunately I don't know what the combination of keys are, so I am struggling to find out more about this behaviour on my own and I was hoping that someone has

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 all, Does anyone have any idea on how to speed up the for() loop below. Currently it takes approximately 2 minutes and 30 seconds. Because of the size of Nsim and N, simulating a multivariate normal (instead of simulating Nsim times a vector of N normal distributions) would require too much memory space. Many thanks for your kind help, Simona N=3000 PD=runif(N,0,1) cutoff.=qnorm(PD)

Hi, Given a function fun <- function(a, b) a + b how do I generate the function 'function(x, y) x + y'? 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.

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, I have a basic question about aligning date labels for the x-axis in an xyplot so that they align with the grid lines from the panel.grid argument. For example, with x <- data.frame( date = seq(as.Date("2005/01/01"), as.Date("2006/06/01"), length.out = 20), value = runif(20)) xyplot(value ~ date, data = x, panel = function(x, y, subscripts, ...) {

Here's one not-so-straightforward way: > f <- function(a, b) a + b > flist <- as.list(f) > names(flist)[1:2] <- c("x", "y") > flist[[3]] <- do.call("substitute", list(body(f), list(a=as.name("x"), b=as.name("y")))) > g <- as.function(flist) > g function (x, y) x + y HTH, Andy > From: john.gavin at ubs.com

Hi, I am probably making a simple mistake but I can't see it > X Error: Object "X" not found > exists("X") [1] FALSE > lapply("X", exists) [[1]] [1] TRUE Why is lapply producing true? Is it something to do with the first argument of lapply also being called 'X'? > version _ platform i386-pc-mingw32 arch i386

Hi, V1.8.0 seems to allow DateTimeClasses as the x argument in xyplots (lattice). For example: x <- seq.POSIXt(strptime("2003/01/01", format = "%Y/%m/%d"), strptime("2003/10/01", format = "%Y/%m/%d"), by = "month") y <- rnorm(length(x)) dat <- data.frame(x= x, y = y) xyplot(y ~ x, data = dat, type = "b")

Dear R-users, How do I obtain a sequence of dates consisting of only weekdays without the weekends in R? In S, I can do the following: timeSeq(from="12/17/2007", to="8/25/2008", by="weekdays") I tried using looking at timeSequence (fSeries package) and seq.Date (base package) but I do not know if I can specify "weekdays" rather than "day".

Hi, I use the excellent Sweave tools for writing documents but was wondering how to neatly print a data.frame with long column headings. I cant manage to do this via package:xtable. Typically the labels that I would like use for each column consist of more than one word, but even with just one word, the heading is often wider than the contents of the column. So the number of columns that fits

Hi, I recently encountered a similar problem to http://www.mail-archive.com/r-help at stat.math.ethz.ch/msg31960.html One conclusion from that thread seems to be that if XP users need to update the index, after installing a package, they have to install R into a directory for which they have got write access, either a network or local drive. This is in order to update the files 'C:Program

Hi, I would like to use Sweave to document a long function. Is it possible to split the function's code into chunks such that Sweave will accept each chunk without complaining. I have tried various approaches without sucess but I feel sure that someone has done this already. Here is one attempt ============== % First, define the funciton header <<defFunHdr, eval=FALSE>>= x <-
