{again a message that was sent to owner-r-help (which is me, currently) why on earth ???!??!? reply to R-help or the original sender Brett Presnell; } I'm teaching a categorical data analysis course this term, and a minor "problem" has resurfaced that I have often thought about before. This applies equally to Splus I suppose, but my undergrads aren't using Splus. It

Just a few documentation "bugs" that I've noticed recently. 1. In the help for (dpqr)weibull(), the formula given for the variance of a Weibull is wrong. The correct formula is b^2 * sqrt(gamma(1 + 2/a) - (gamma(1 + 1/a))^2)) Note that I've also changed Gamma to gamma, which I think is preferable since this is actually the name of the gamma() function

Hello As I'm beginning to write functions, I decided to have my personnal R library named MyStuff located in /home/fred/R.Lib/MyStuff/ The library file itself is at /home/fred/R.Lib/MyStuff/R/MyStuff evrything seems ok since > library() gives : Packages in library `/usr/lib/R/library': KernSmooth Functions for kernel smoothing for Wand &

Hi Peter and others, If it helps, I wrote a small function glm.scoretest() for the statmod package on CRAN to compute score tests from glm fits. The score test for adding a covariate, or any set of covariates, can be extracted very neatly from the standard glm output, although you probably already know that.

I'll start with my apologies to Martin for sending those last two of message to the list owner (the last one he forwarded was actually sent a week or two ago and must have been lost in the ether somehow). This is basically due to fast copy/paste in emacs without paying much attention to what I'm doing. Lack of sleep is my excuse, but I don't know if that goes very far with the

This might more properly be filed as a bug report, but ... I came upon the following problem while trying to dyn.load a library of Fortran code into R. I'm running RedHat 7.1 on a Pentium III laptop, with R version 1.3.1 (latest rpm from CRAN) and gcc/g77 version 2.96. My library has a number of Fortran subroutines that have underscores in their names for readability. By default g77

How difficult would it be (I could try myself if someone thought it would be straightforward) to change read.table to allow a comment character such as # or %? My thought would be that anything on a line following a comment character would be ignored (so that the combination of blank.lines.skip=TRUE and a comment at the beginning of the line would lead to a line being skipped completely).

--fupGvOGOQM Content-Type: text/plain; charset=us-ascii Content-Description: message body and .signature Content-Transfer-Encoding: 7bit There's a simple bug in the handling of the start and offset arguments in glm and glm.fit. The bug exists in the latest development version of R (version information below), but it appears that glm.R has not been touched much lately, so the bug affects at

In looking over the bugs list, it seems to me that most of them are things we can no longer do anything about, because they are on old versions or broken systems or were features or .... There are now so many they obscure the bugs needing attention. I am about the remove the following. If anyone thinks they are still relevant, could you please send a follow-up to R-bugs with details under 1.2.0

Seems to be a day for finding peculiar little things. There is an inconsistency in the behavior of lm vis a vis glm: > x <- rnorm(15) > y <- 1 + 10*x + rnorm(15) > z <- as.factor(rep(c("A","B","C"),rep(5,3))) > xyz <- data.frame(x,y,z) > fit.lm <- lm(y ~ x + z, data=xyz, subset=(z != "C")) > fit.glm <- glm(y ~ x +

I'm posting this for two reasons: one is to see if anyone has a better way of solving the problem or suggestions for improving my existing approach; and the other is to show what I'm currently doing in case anyone else might find it useful. The background is that I've been using Sweave for several years now to produce class notes, and I sometimes include quite a lot of raw R input and

How exactly should I go about turning off annotation when running Stangle (Rtangle) with "R CMD Stangle myfile.Rnw"? Ideally I would like to be able to turn annotation off and on for individual code chunks, or maybe better, to annotate only named chunks. Are either of these things easily done? Is there some way to figure out this sort of thing without reading through the source code

Hi I would like to start by thanking everyone that replied. Thank you for the information, and for the comments about how or why you use it and thankx for the encouragement re my talk.... Please note that I do not claim to have ellicited a reply from all users of R, this is a quick survey not a census. I have tried to break the responces down to the following categories: Where: (hopefully

Hello, I'm a new user of R, and unsure of why I'm getting an error reading external files on my Mac OS 10 machine. I've read through posts that would seem related (and 'R Import/Export' and 'Introduction to R' as well as pertinent sections in V&R's 'Modern Applied Statistics with S-Plus') but to no avail. If anyone has any suggestions,

The build system rolled up R-3.5.2.tar.gz (codename "Eggshell Igloo") this morning. The list below details the changes in this release. You can get the source code from http://cran.r-project.org/src/base/R-3/R-3.5.2.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course. For the R Core Team, Peter Dalgaard

Thanks to all who responded. Not all of the advice helped me with that particular problem, but, I have learned a lot just from your answers. 1. R for Mac 10 (Carbon version) uses the Mac convention of using ":" for the usual Unix "/" and thanks to Dr. Lumley for that since I'm new to R, Mac10, Macs in general, and Unix. 2. Interestingly, Dr. Ripley suggested to

I appreciate Brian and Martin's answers -- and I certainly don't spend as much time & energy maintaining and answering questions about R as they do -- *but* it does seem to me that it would make a number of new (switching) user's lives easier if there were a succinct list of these differences, with a disclaimer ... I would be willing to maintain such a list, but since I

Hi, I thought it would be convenient if the check.names argument to read.table, which currently can only be TRUE/FALSE, could take a function value as well. If the function is supplied it should be used instead of the default make.names. Here is an example where it can come in handy. I tend to keep my data in coma-separated files with a header line. The header line is prefixed with a comment
