I just ran into this strange behavior. y <- rnorm(1000) x <- seq(0, length=length(y)) plot(x, y, type='l', lty=1) - instantaneous plot(x, y, type='l', lty=2) - 18s plotting lines + 15s plotting axes = 33s plot(x, y, type='l', lty=3) - 76s ,, + 75s ,, = 151s plot(x, y, type='l', lty=4) -

Hello all, I have a very simple set of data and I would like to analyze them with probit analysis. The data are: X Event Trial 100 8 8 75 8 8 50 6 8 25 4 8 10 2 8 0 0 8 I want to estimate the value of X that will give a 95% hit rate (Event/Trial) and the corresponding 95% CI. Anyone can offer some help? Thanks!! -

Is there any way to process the "vignette" documantation files? I have been looking at the bioconductor packages and most of them have *.Rnw files in doc directories. They look like regular TeX but have sections showing R code that seem to choke TeX.

Hi, I am not sure if this is a bug, so I am posting it here. I also searched the FAQ file for the readline string and did not find anything about the behavior below. I just successfully rsync'ed, compiled and tested R-1.4.0 on my RH 7.2 Linux machine. I encountered one problem though. When running ./configure I noticed that I was getting errors from the readline library. Although

I just installed R-1.4.0 on my Win2k machine from SetupR.exe. Everything seems to be fine with the base and recommended packages. However, when I install the lattice and grid packages they do not seem to work. Everything I try results in something like this: Instruction 0x00543f06 refernced memory 0x00000000. The memory cannot be "read". and I am getting kicked out of R. Has

I think that there is a bug in the as.POSIXct function on Windows. Here is what I get on Win2000, Pentium III machine in R 1.8.1. > dd1 <- ISOdatetime(2003, 10, 26, 0, 59, 59) > dd2 <- ISOdatetime(2003, 10, 26, 1, 0, 0) > dd2 - dd1 Time difference of 1.000278 hours Now, the 26th of October was the day that change to the standard time occurred, so I suspect that this has

I am about to get a new machine at work - an IBM Intellistation with the Xeon 2.8 GB processor. It will run Windows 2000. I would like to install the proper ATLAS dll for this machine, but I am not sure if Xeon is P4? Does anybody have any experience with Xeon?

Hi, I am trying to compile R-1.3.1 under RH-7.2 Linux. I used the old gcc compiler (kgcc) and the compilation went fine. I can start R and run some rudimentary tasks with no problem. However, when I did make check I got the following error in base-Ex.Rout > fa <- file.access(dir(".")) Error in file.access(dir(".")) : file.access is not implemented on

Hi, I have a problem of estimating a mixture of two normal distributions. I need to find the starting points automatically, since this is a part of a larger piece of image processing code. I found the mix2normal1 function in VGAM package that mentions a method of finding starting values for mu1 and mu2 but refers the reader to a book by Everitt and Hand. Unfortunately, I do not have an easy

Hi, This seems a very basic problem, but I cannot seem to find the solution to it. I am trying to use Rcmdr on a data frame I created in my current R session. More specifically, I did x <- data.frame(matrix(0, ncol=3, nrow=5)) library(Rcmdr) Now I would like to be able to edit, view and perhaps analyze x, but I cannot seem to figure out how to make it active. Any hint will be welcome.

I am not sure if this is already known. I checked BUGS and found some references to similar behavior when R_HOME is set? Here is what I get: (1) Fresh build of 1.4.1 under Linux/RH-7.2. All tests pass. > R CMD check ctest * checking for working latex ... OK * using log directory `/home/andyj/stat/R-1.4.1/library/ctest.Rcheck' Installing *source* package `ctest'

A couple of days ago a few messages indicated that something changed in the basic plot routine that made plot(*, type='l') slow for large data sets. Some people even reported crashes for very large data sets. As far as I remember, this was not reported as a formal bug. I am still not sure if this is a bug, so I report my findings here. First of all, I think I see a slowdown of the plot

Hi, I just installed the odesolve package and ran the check command on it. It failed trying to execute library(gnlm). Sure enough, there is no gnlm library on my system and I could not find it on the CRAN archive either. Am I missing anything obvious or is gnlm some private library that somehow found its way into the example section of odesolve? Thanks in advance, Andy

I also downloaded the rgl package (after reading recent Uwe Ligges' post) and installed in on my Win2k Pro sp2 machine. It seems to work with no problems. I ran most of the examples, including the hist3d one, and all of them worked fine. A couple of thoughts. I have administrative priviliges on my machine. Could this possible make a difference. The rgl library uses OpenGL. Is it a

Hi, I have the following question about creating data frames. I want to create a data frame with 2 components: a vector and a matrix. Let me use a simple example: y <- rnorm(10) x <- matrix(rnorm(150), nrow=10) Now if I do dd <- data.frame(x=x, y=y) I get a data frame with 16 colums, but if, according to the documentation, I do dd <- data.frame(x=I(x), y=y) then str(dd)

I wonder how one in R can fit a 3rd degree polynomial to some data? Say the data is: y <- c(15.51, 12.44, 31.5, 21.5, 17.89, 27.09, 15.02, 13.43, 18.18, 11.32) x <- seq(3.75, 6, 0.25) And resulting degrees of polynomial are: 5.8007 -91.6339 472.1726 -774.2584 THanks in advance! -- Jonas Malmros Stockholm University Stockholm, Sweden

This is (hopefully) a small request. I routinely build (and test) both R versions from sources on my system (WinXP). I would like to be sure that I have the current version of Rtools. I always go to Robert Murdoch's site "Building R for Windows" and check the latest news. Everything I need is explained there, except I never know if I have the most recent version of Rtools.exe.

Hi, I am trying to install R on Windows. I copied the set up binary. But it is corrupted on all the mirror sites. Please let know an alternative for getting the software. Thanks, Sai

I am having a problem with a gantt chart since moving to R2.4.0. from 2.3.1 I made some adaptations to the code from http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=74 and successful produced a simple gantt chart. However when I upgraded to 2.4.0 it no longer works as desired. See http://ca.geocities.com/jrkrideau/R/gantproblem.pdf for the two charts. The charts were produced

Hi, I encountered this problem just before the 2.2.0 release. Then it went away for a while and came back at the beginning of this week. Here is what is happening (I am on Win2000 machine with all the necessary tools installed). I compile R-devel and R-patched trees every couple of days and install them in separate directories. Everything seems to work fine for R-patched. Compilation of
