Dear R Helpers, Does anyone know how to use tcltk to display jpeg images? The manual says that one must use Tk_PhotoCreateImageFormat to register the jpeg image handler. The "ActiveTcl User Guide" (http://support.serv.ch/lang/tcl/img/doc/img-jpeg.html) says:- "The package img::jpeg is a sub-package of Img. It can be loaded as a part of the complete Img support, via package require

Hello, I am looking for more information about lazy loading introduced in R 2.0.0. Doing ?lazyLoad I got some and there is a 'see also' section that points to 'makeLazyLoading'... But I cannot reach this page. My problem is: I recompiled a library that uses a lot of functions from other libraries (of course I can give details if needed). I load it in my computer: library(svGUI),

Dear List.... sorry to bother you R-gurus with such an "unstatistical" question... but I face a problem using Crimson Editor with R 2.01.1 that I never had using R 2.00.1. I already posted on the Crimson Editor forum but it seems to be VERY few R-users there....

Hello, Sorry if this question was already asked (I though it was... but did not found the exact answer in the archives).

Hello, I try to set up namespaces for packages. It is fine for several of them, except one whose compilation fails (under Windows XP & R 2.0.0): ---------- Making package svViews ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata Error in parse(file, n, text, prompt) : syntax error on line 21 Execution halted make[2]: *** [nmspace] Error 1 make[1]: ***

Having just discovered "Task Views" I see there isn't one for ecology/environmental science. I don't have the expertise to help with this, but I think it would be a very useful addition if there was any person (s) on the list willing to help create such a Task View. I am sure the maintainers of the Task Views will pick up on any responses to this post from volunteers. I

Hello, Thanks to Douglas Bates, there is now a new benchmark suite (version 2.3) which is compatible with R 1.9.0 and the recent Matrix library (0.8-1 or above). You find it at http://www.sciviews.org/other/benchmark.htm. It compares R 1.9.0 under Windows with: S-PLUS 6.5, Matlab 6.0, O-Matrix 5.6, Octave 2.1.42, Scilab 2.7 and Ox 3.30. In short, R in its version 1.9.0 and with the new Matrix

Dear R-devel & Translation Teams, In order to monitor the progress of the translation for the pt_BR team I wrote a script to summarize the status of the translations. It wasn't difficult to extend it to the other languages so I decided to set up a page with the summaries of the translation for all languages for which currently exist a translation.

Hello 1. a few months ago, I had sciviews working fine with R (rw2001) under windows XP 2. now, upgrading to rw2011, the stuff seems fine (every package installed),but I find a conflict when launching sciviews: - it runs, apparently - but when I try to work ("import/export In: text" for instance), it asks for Rcmdr ("Would you like to install it now?") 3.

Hi netters, I want to learn a decision tree from a series of instances (learning data). The packages tree or rpart can do this quite well, but the scoring functions (splitting criteria) are fixed in these packages, like gini or something. However, I'm going to use another scoring function. At first I wanna modify the R code of tree or rpart and put my own scoring function in. But it

Hi, I am doing some research on feature selection for classfication problem using genetic algorithm in a wrapper approach. I am wondering if there is some package which is already built for this purpose. I was advised before about dprep package but I don't think it used GA there (if I am wrong, please correct me!) Thanks, Ed

This is a TINN-R editor question rather than an R question, but can anyone tell me how to use command line flags with TINN-R. There is a space to fill in the path to Rgui, and I have "C:\Program Files\R\rw2001pat\bin\Rgui.exe". If I try to add a command line flag after that, such as " --no-save" or " --max-mem-size" then TINN-R will not open the application.

Actually I am trying to run sciview-R and encounted some problems with tk, and I thought I'll check the basic library(tcltk) functionallity, just to be sure.
