With Tony Rossini's help we have established anonymous CVS access to a read-only copy of the main R CVS tree at cvs.r-project.org. This would be of interest primarily to those who want to track the development version (and who have access to CVS, of course). To use anonymous cvs you must log in to the server under the name "anoncvs" and with the password "anoncvs". You

Does anyone know of any comprehensive literature (like a book, collection of articles, etc.) that walk thorugh example of ARIMA modeling with the ts package of R? Genarlly if you've just started to learn the R-language and are all week long with ARIMA, what is a fast-pace source that you would recommend (to a beginner) ? Thank you, Krasi

I'd like to make axis titles, chart titles, legends and the like mathematically nice (e.g., have proper superscripts and subscripts, variables in italics, and so on). Ideally, one could go into ``math mode" a la LaTeX, and write something like plot(blah, xlab="Methane in $\mbox{cm}^3$ / g", blah). This is just an ideal, but it would be nice. Is some approximation of this

Hey everyone, What am I doing wrong? I loaded the MASS package with library(MASS), and now when I type library() I get > library() Packages in library `F:\r\rw0651/library': MASS Main Library of Venables and Ripley's MASS base The R base package . . . That's fine. The problem is that when I try to use a function that I know is built

Sorry to ask this but does anyone knows a good text that helps with the basic programming side of R. I understand the statistics behind most of R but i have real difficulty with the data types and how R views them. As a part of that could you help me with another problem. I know how to read data in from a file in terms of read.table but how do i single a column out or even just download a

I have sort of an emergency question for the list. One of my professors for an S-Plus intensive class distributed a function to produce partial regression plots. I need to run it under R, because I'm doing the homework on my home computer with a modem; hence I don't have the speed required to emulate X-Windows and run S Plus off one of the campus servers. Bottom line: I'm using R.

Hello! I have something like this: test1 <- data.frame(intx=c(4,3,1,1,2,2,3), status=c(1,1,1,0,1,1,0), x1=c(0,2,1,1,1,0,0), x2=c(1,1,0,0,2,2,0), sex=c(0,0,0,0,1,1,1)) and I can easily fit a cox model: library(survival) coxph(Surv(intx,status) ~ x1 + x2 + strata(sex),test1) However, I want to

I posted this to the sci.math newsgroup but didn't get any responses so I was hoping someone here could help. I have a number of items with "distances" of differences between each other. What I want to do is to plot each item on a two dimensional plot such that the positions on the plot indicate the approximate distance between each item. What I want to look at, basically, is a map

Potentially Stupid Question Department: I just tried to load a few packages in a row. First I loaded MASS, then tseries, then nls. A typical error message from the last two looked like this: Attaching Package "package:nls": The following object(s) are masked from package:MASS : profile Is this a big deal? Does it mean that I lose any functionality from the

Hey everyone, Might it be possible for future versions of PC-R to highlight the opening brace in a pair, a la emacs? Programs that do that are infinitely friendlier than those that don't. Thanks, Steve Stephen R. Laniel | "I've got a match: Carnegie Mellon University | Your embrace and my collapse." laniel at cmu.edu | --They Might Be

Hello, I recall reading a thread months ago on this mailing list about handling very datasets under R, but I can't seem to find it. This has become particularly important recently, because I've been playing with a dataset containing information about every fatal car accident in the U.S. since 1975; in total, the relevant files are about 120 megs. I'd like to load all of these into R

Dear R users I am new R user, execuse me I bother you, but I worked hard to find a solution: # data ID <- c(1:100) set.seed(21) y <- rnorm(100, 10,2) x1 <- rnorm(100, 10,2) x2 <- rnorm(100, 10,2) x3 <- rnorm(100, 10,2) x4 <- rnorm(100, 10,2) x5 <- rnorm(100, 10,2) x6 <- rnorm(100, 10,2) mydf <- data.frame(ID,y, x1,x2, x3, x4, x5, x6) # just seperate analyis

Dear developers, I wonder would you consider making a save to a graphics file format (as opposed to ps)? What prompts this is that we have just finished my wife's thesis using R heavily for stats and graphs. The combination of latex, bibtex and R generated .eps worked a treat and we were very pleased with both the final outcome and the efficiency of gernerating it, especially when all the

Hi, I have a catalog that has images in it. The images are stored in public/images/.... When I open the catalog via the catalog controller I get this url: http://127.0.0.1:3000/images/sow/sow.jpg for the images and they display correctly. When I link to the catalog from another controller and view I get this: http://127.0.0.1:3000/catalog/images/sow/sow.jpg If I attempt to put and image

I''ve got a single puppet master (2.7.19 + facter 1.6.11) controlling a number of nodes (2.7.17 + facter 1.6.8-10). On all of thse, fact absed variables work as expected (such as $::operatingsystem and $::fqdn). However, on my puppet master, when I run ''puppet agent --test'' all fact based variables are combing back as empty strings. For example. I have a line in a

I?m looking for advice and considerations on how to optimally setup and deploy an NFS-based home directory server. In particular: (1) how to determine hardware requirements, and (2) how to best setup and configure the server. We actually have a system in place, but the performance is pretty bad---the users often experience a fair amount of lag (1--5 seconds) when doing anything on their home
