R developers, 2 things: a bug in model.frame and a question about setup of generic functions. I don't understand the following behavior for generic functions: Suppose I'm working with the cats data in the MASS library and I want to create a formula object to model Hwt on Sex: # This works: > formula(Hwt ~ Sex) Hwt ~ Sex # But the following does not: > formula(Hwt ~ Sex,

Dear R-help-ers (Currently running Version 0.65.1 Release (October 07, 1999) on Solaris 2.6) My problem has to do with updates of the R language. When I install a new version, I would like to just change one directive, or a soft link to the current doc/html/ directory, to update a bookmark I have pointing to the current R doumentation directory. I've tried building a soft link:

Hello- Does anyone have a recommendation on how to call R from perl? I'm using the IPC::Open2 module, and running R with the --slave and --quiet options. The problem is that I can't predict how many lines of output I should try to read for each command-- if any! The ultimate goal is to use perl to provide a form-driven web interface, but have R do the underlying calculations. Thanks

Using diag() to extract the diagonal of a matrix loses all but the first dimname (R 0.62.3). The problem seems to be in [ ]: > > x <- matrix(1:9,3,3) > dimnames(x) <- list(c("a", "b", "c"), c("a", "b", "c")) > x a b c a 1 4 7 b 2 5 8 c 3 6 9 > diag(x) a NA NA 1 5 9 > x[c(1,5,9)] a NA NA 1 5 9 > Paul

Hello, I want to fit some non linear models with the Levenberg-Marquardt algorithm. It doesn''t seem to exist any function to do this in R ( well, maybe one does, but I''m a new user, and the only documentation I have is "An introduction to R"). I''d like to know if this function exists, maybe throught an additionnal package. I''d also like to know if if

Hi, there, S+ has a function leaps which can be used for criterion based model selection. Is there an equivalent function in R? thanks in advance.

I have been trying to get a working version of ar, since I have used it in several calculations in the test suite for my time series library. The following limited version (order.max must be specified and other short comings) works more or less, but the results differ by more than I would expect from those given by Splus. I have tried several variations with no success. If anyone can see a reason

Hi, I am running Debian Sid. I am having trouble with the R packages. Executing 'help()' or 'demo()' launches 'most' with no text. 'help.start()' works properly. When I try to install a package, I get the following problem: ********************************************************************* > install.packages("ctv") Installing package(s) into

I want to create a grid of function values for use in `contour' or `persp'. The function is the log-likelihood for the gamma. The sample is stored as vector of length 20 called `Survival'. A single evaluation of the log-likelihood at, say, scale = 9 and shape = 10 would be obtained by sum(dgamma(Survival, scale = 9, shape = 10, log = TRUE)) (This may work only 0.99.0, I'm not

Dear Rhelp folks, I think I read this in recent Rhelp, but I can't find it in the archive. I need to know how to get lg2c in order to build the nlme package. I'm trying to install nlme_3.1-2.tar.gz on a Linux machine (6.1 Redhat) under R Version 0.99.0 (February 7, 2000). Thanks, Jim Jim Robison-Cox ____________ Department of Math Sciences | |

Hello, Perhaps this is a bug, but I thought I'd start with R-Help. I'm trying to compile R-1.4.1 on a new Sun-Blade running Solaris 2.8 ( I got it running with no problem on older SUNs) I get the following error after doing the usual ./configure and make: gcc -I. -I../../src/include -I../../src/include -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -c arithmetic.c -o arithmetic.o

Just after R-0.63.0 came out I reported a problem to the list. I was unable to get ./configure to complete it's job, because it couldn't find a working fortran. It stopped after trying to test for underscore in subroutine names. This was especially perplexing, since I could still configure the older version (I had 62.2) with no error messages. I tried suggestions of B.D. Ripley and

Dear R-helpers, I just upgraded from version 62.1 to 62.2 and now am faced with the same problem I've run into before when upgrading: Is there an easy way to take the libraries I have been using in the older version and pull then into the new version. My organization looks like this on Solaris 2.5.2: /opt -- /R -- /R-0.62.1 --/library -- subdirectories for lots of

To R-devel: If anyone is testing the aov() function and it's relatives which I posted to the list, thanks for the effort, but I would ask you to hold off now. Brian Ripley is developing better and more complete versions, so you should save your effort for looking over his functions. His preliminary version is located at: http://www.stats.ox.ac.uk/pub/R/aov.tar.gz Prof. Ripley says

Hello List, Knowing I would eventually need to ask for help on the list, I've held off my thanks and congratulations on the 1.+ releases of R. I am amazed at the dedication of the R-core team, and do add my applause and thanks. I've had a compile problem with the latest version which has not occurred before. I'm compiling under: platform sparc-sun-solaris2.6 arch sparc
