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

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.

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

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.

Hi Philippe and R community, I am trying to use some functions from the svDialogs package but I get some werid errors I do not understand: > library(svDialogs) > m_list <- as.list(1:10) > guiDlgDoubleList(m_list, m_list) Error in guiDlgDoubleList(m_list, m_list) : Not yet implemented! > guiDlgList(m_list) Error in guiDlgList(m_list) : couldn't find function

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. Rcmdr is already

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.

Hi, I need to run a burdensome simulation. I'm using a Dell PowerEdge 2850, 3.8 Ghz CPU, 2 Gb RAM, Windows server 2003, 32 bit. The task manager indicates that Rgui.exe is using 25% of the CPU speed. There is no other process that is slowing down R. Does anyone know if it's a limitation of R? If so, can I set up the program for the CPU usage like I do for the memory usage? Is there a

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

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.

Hi, I would like to be able to use R with a connection to a PostgreSQL database. I am using R 2.0.1 on windows XP. I have tried installing both the DBI and rDBI packages (which is better?) but in either case I run into the same problem - when i try to use either the dbDriver or dbConnect functions i'm told the function couldn't be found. Seems like the packages aren't installing

Hi, I have data on stomach contents. Possible prey species are in the hundreds, so a list of prey codes has been in used in many labs doing this kind of work. When comes time to do analyses on these data one often wants to regroup prey in broader categories, especially for rare prey. In SAS you can nest a large number of "if-else", or do this more cleanly with "select"

In this years biostat teaching I will include Rcommander (it indeed simplifies syntax problems that makes students frequently miss the core statistical problems).
