In fact my first vignette full stop. I am intending to use Sweave. I have read the Sweave documentation and section 1.4 of the extensions manual and apart from (a) do not use split = TRUE (b) and include all the source components, there does not seem to be anything CRAN specific. 1 - Am I missing some other documentation? 2 - If I use a package from CTAN would that be considered within the

There are occasional comments on this list about how difficult it is to read the digest format. Since it took me a few false starts to configure my mailer to do it I have (with the encouragement of the list owner) put together a few hints. All I need now is for people who use other mailers to fill in the details in the same way as I have done for Eudora. The draft is available at

If I am buying a PC where the most compute intensive task will be running R and I do not have unlimited resources what trade-offs should I make? Specifically should I go for 1 - more memory, or 2 - faster processor, or 3 - something else? If it makes a difference I shall be running Windows on it and I am thinking about getting a portable which I understand makes upgrading more difficult. Extra

When I go ?reshape I get told, amongst other things new.row.names logical; if TRUE and direction = "wide", create new row names in long format from the values of the id and time variables. This seems to me to be illogical, surely it should read direction = "long"? Reading the code and observing its behaviour I find that (a) the default for new.row.names is in fact NULL (b)

Hi all, The problem is that when you try to use the function summary of a polr object in a function, it does not work. The problem is not related to the formula or the structure of data involved. It is probably related to the use of the function "vcov" in the code of summary for polr, and the iterative procedure to estimate the Hessian. Anyway, here there is an example extracted from

Something about the way R processes backslashes is defeating me. Perhaps this is because I have only just started using R for text processing. I would like to change occurrences of the ampersand & into ampersand preceded by a backslash. > temp <- "R & D" > sub("&", "\&", temp) [1] "R & D" > sub("&",

Short version If I have a data frame X and I suspect that there is a dependency between the columns how do I confirm that, and how do I tell which subset of columns is involved? ================================== Long version A colleague had been trying to use the SPSS RELIABILITY procedure. It told her that the determinant of the matrix was small. She asked me what that meant and I told her

I have been successfully been using R on my EEE PC for some while now. Although it uses Xandros I have been able to install various pieces of software by pretending that it was Debian etch. Johannes was kind enough to continue providing binaries on CRAN for a while but I think I am the only person still living in the past as CRAN etch is currently stuck at 2.11.0 and I cannot rely on him to

I have recently acquired an Asus EEE PC which runs a version of Xandros which I believe to be a fork of Debian. I have been using R under various versions of Windows for some years but this is my first move into the world of Unix. I have installed Texlive from a CD and I have successfully added a UK-based repository and installed Texmaker. Now I would like to add R. There are dire warnings on

The outcome variable in my dataset is cost. I prefer not to transform it as readers will really be interested in pounds, not log(pounds) or sqrt(pounds). I have fitted my model using lme and now wish to use boot on it. I have therefore plagiarised the example in the article in RNews 2/3 December 2002 after loading the dataset I source this file

When I run R CMD check on a package I have recently started work on I get the following: * checking R code for possible problems ... NOTE addlinear: no visible binding for global variable 'x' I appreciate that this is only a NOTE and so I assume is R's equivalent of 'This is perfectly legal but I wonder whether it is really what you intended' but I would like to understand

I have a series of question about methods and generics. The questions are interspersed in some text which explains what I want to do, how it works now and why I do not understand well why it works. Questions are written Q1 and so on up to Q9 and always start a new line. The concrete problem is this: it has become customary after a meta-analysis to quote various statistics to give a picture of the

The concrete problem is that I am refereeing a paper where a confidence interval is presented for the risk ratio and I do not find it credible. I show below my attempts to do this in R. The example is slightly changed from the authors'. I can obtain a confidence interval for the odds ratio from fisher.test of course === fisher.test example === > outcome <- matrix(c(500, 0, 500, 8),

Hi (Duncan?), The other day I noticed some characters will cause errors in R CMD CHECK because of parse_Rd(), and AFAIK, these chars include '%', '{' and '}'. For example, note the comments in the example section: %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% \name{testfun} \Rdversion{1.1} \alias{testfun} \title{ A Test } \description{ A test } \usage{ testfun() } \value{ NULL }

Folks I have a new laptop running Centos 6.2 64-bit. I'd like to put a virtual machine running Windows 7 (licensed), with full audio/video functions, and good response. Which virtual system would you recommend? I can think of KVM, or VirtualBox, or ...? The "good response" requirement pretty much excludes a web-style video presentation. Opinions solicited.

Hi all, one of our clients have three branch offices currently connected by ADSL lines. they are using Cisco 827-4V units with the FXS ports connected to their aging PBX units. I am thinking of installing an * server in the head office, maybe with an analogue FXO card connected to the PSTN so field officers in Melbourne can call sydney for a local call price. The question is - what Digium

I have a remote home server updated to CentOS-7.2.1511 (as stated in /etc/redhat-release) but I have not re-booted since the update. The machine is currently running kernel 3.10.0-229.11.1.el7.x86_64. I'm wondering if anyone has advice on any safety steps I can take before re-booting, so that in the event of failure I can give simple instructions to my daughter at the other end on how to get
