In R-beta (Masked Marvel), when I do the example from the read.pnm help file, this is what happens: x <- read.pnm(system.file("pictures/logo.pgm",package="pixmap")[1]) Warning message: In rep(cellres, length=2): x is NULL so the result will be NULL In R-2.15.3, it's all right.

Hello! Over the weekend, I updated my RcmdrPlugin.qual package. It works fine on a 64 bit Windows machine but not a 32 bit. This is very strange. The new menu with all of the Quality Control stuff does not appear. Have any of you run into this sort of thing before, please? Thanks, Sincerely, Erin Erin M.

Dear list, following a previous querry we are still stuck! As pointed out by Erin Hodges the "ts" library includes a PACF function which reports the partial correlation of population density at time t against lagged population density. However, what we are trying to calculate is the partial correlation between rate of population change, Rt=log Nt/Nt-1, against lagged population

Dear R People: I have a question about a "sorting" problem, please. I have a vector xx: > xx [1] -2.0 1.4 -1.2 -2.2 0.4 1.5 -2.2 0.2 -0.4 -0.9 and a vector of breaks: > xx.y [1] -2.2000000 -0.9666667 0.2666667 1.5000000 I want to produce another vector z which contains the number of the class that each data point is in. for instance, xx[1] is between xx.y[1] and

Dear Debian People: Is there a way to run a little script (on Ubuntu Manic Meerkat) every hour, please? I know that this is more of a LINUX/UNIX question rather than an R question. Sorry.

Dear R Debian People: I have put this on regular R help as well, but thought that I'd try here too. I updated to R-2.10.0 on Ubuntu Karmic Koala via apt-get update, apt-get install. Then I had a problem that said that I need MASS <= R-2.9.2. Fair enough. Uwe Ligges was kind enough to point out that I needed to use > update.packges(checkBuilt=TRUE) So I did. Now the menu on Rcmdr

Hi again. On Windows, when I try to use the "install packages" from the menu, there is no Rcmdr and no RcmdrPlugins to be seen. thanks, Erin Erin M.

Dear R Developers: Why is it that the singular value decomposition is used when running regression with arima, please? I've been looking for a reference for that but have come up empty so far. Thank you for any help. Sincerely, Erin Erin M. Hodgess, PhD Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: hodgesse@uhd.edu

Dear R Development People: I was trying to build R-2.12.2 from source on a Windows XP machine. Doing the make all recommended works fine, but building the bitmap dll is a problem. It seems to be in the libpng directory. I got libpng-1.5.1, and untarred it. However, there is no makefile.mingw file in the scripts directory. I then obtained a version of libpng-1.4.5, and the file is there.

Dear R Development People: I have written a couple of plugins for Rcmdr and they do not seem to work with R-2.11.0.

Dear R People: I have R Version 0.90.1 for UNIX (binary) and the Windows version from a binary distribution as well. I would like to look at the source code for the C program setup_starma in the ts library. How would I find that, please? Thanks in advance. Sincerely, Erin M.

Dear R People: I'm having some trouble with mpiexec and Rmpi. I would like to be able to pass in the number of "children" via the mpiexec command (from the command line). this is in SUSE10.1, with R-2.7.1 Here are my files: cat eb.R library(Rmpi) mpi.remote.exec(paste("i am",mpi.comm.rank(),"of",mpi.comm.size())) mpi.quit() hodgesse at

Hi, I'm trying to go through the examples for function arima0() in ts package, i.e, >data(lh) >arima0(lh, order = c(1,0,0)) each time the call to arima0() causes a segmentation fault. I checked the earlier version (1.1.1) of R, the function arima0 works fine. Tracing the call indicates that the function "setup_starma" (in pacf.c under ts) interprets the addresses of the

Dear Sirs, I am a new user of the R package. When I try to use the curve function it confuses me. > curve(x^2) Works fine. > curve(x) Makes a complaint I don't understand. Why is x^2 valid and x is not? I check the documentation of curve, and it says the first argument must be an expression containing x. > expression(x) Is an expression containing x. > curve(expression(x))

R community, As you may know, R's iconv doesn't work well converting to and from encodings that allow embedded nulls. For example > iconv("foo", to="UTF-16") Error in iconv("foo", to = "UTF-16") : embedded nul in string: '\xff\xfef\0o\0o\0' However, I don't believe embedded nulls are at issue here, but rather that R's iconv

Hello, Could anyone tell me what rules R uses to classify an autoregressive model i.e. how it decides the number of AR parameters to use when the AR(data) function is applied? I understood that model classification was more or less based on inspection of the acf and pacf functions. Thanks TT -- View this message in context:

Hello, I spent quite some time now searching for any hint that R can also be used to address the interfaces of a computer (i.e. RS232 or USB) to acquire data from measurement devices (like with the - I think it is the - devices or serial toolbox of Matlab). Is there any package available or a project going on that you know of? I would so much like to have never to work with Matlab again. The

Hi Ryszard! There is a dist function in R. It's in the mva package. You can set the kind of distance that you want. Thanks, Erin mailto:hodgess at gator.uhd.edu
