Hi, I need some help figuring out how to make a pop-up message box appear with error messages when running a script using Rterm. Windows XP R2.10.1 ...possibly with the ability to either continue or abort the script? Thanks. M -- [[alternative HTML version deleted]]

Hi, I've been learning how to use R TclTk in Windows over the last few months. I have recently put together a collection of examples of some common widgets and their corresponding R code, at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ I would be interested in any feedback - Is it useful? Does it contain any significant errors or bad coding style? Does anyone else want to contribute similar examples with screenshots? Regards, James -------------------------------------------------------------------------- James Wettenhal...

Hello, I'm trying to write a function using tcltk to interactively modify a plot and gather locator() data. I've read Peter's articles in Rnews, the help pages in tcltk, http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/, plus a post in R-help sometime ago, but haven't found a solution. The idea goes something like this: require(tcltk) testplot <- function() { getcoords <- function(...) { locator(5) } x <- 1:1000 y <- rnorm(1000) plot(x, y) base <- tktoplevel() loc.pts <-...

I would like to display output to a tcltk window from e.g. a call to summary(). I tried to get something else than oneliners into a text window of the kind found at: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/TextWindows.html But without success.

Has anyone written a matrix editor or data.entry() replacement using the Tk table widget? I've been playing around with the examples at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tktable.html and making some progress, but I'd rather not spend much time on this if someone else has already done it.

I'm trying to create an app using TclTk and R Can someone please explain how I bind a click event to the tree widget (http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/TreeWidget.html) Ideally I'd like to bind to particular elements in the tree but tkbind doesnt seem to work. thanks tom

Hi, as a starting point for using Tcl/Tk in R, I used to refer to James Wettenhall's nicely presented TclTk Examples formerly hosted at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ These days I have been trying to reach these pages but without success. Does anyone know (James, himself, perhaps ;-) whether they are / will be available at some other location --- it would be a pity if not; I found them really useful. Any advice/comment welcome Peter

Hello!! I would like create a window that has diferent element as: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/checkboxes.html http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/radiobuttons.html I know as make it, but I don?t know as I could (align the diferent elemnts to left, right, top, bottom) or (put in a coordinates into windows). If anybody know as I could make it, I would like you say me. Th...

I want to save this input to a variable to use it later on. I was able to do this with a modalDiaglog ( http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/modalDialog.html like this ) but I cannot figure out how to do this with multiple values to be read. I want to run a rather simple simulation and the user has to be able to set multiple parameters (say, number of trials and stimuli). The onOK-function should then "collect" these parame...

But, as you can see by running this code, changing the Name variable using assign does not change the content of the widget. Is there a function to update the content?...

Hello, I am trying to write a tcltk based program that plots/manipulates xts/xoo time series objects.

..., variable= mytkarray) but if I include character strings with embedded spaces, I get braces appearing in the table. I can remove them using a non-R tclarray, (the difference between the first example of http://www.sciviews.org/_rgui/tcltk/Tktable.html and http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tktable.html - the result of the second of which includes the braces (although not in the image provided!) and that of the first does not - but this seems undesirably complicated. Am I missing something simple? Any insights would be gratefully received, Regards, Ruth -- Ruth M. Ripley,...

Hi all, i'm searching for a tutorial on the tcltk extension to R. I've looked at the pages linked to the R web site, and found the examples extremely useful, but I'd like something more. Does anyone know about other documents regarding this subject? Thank you very much ciao luca

Greetings Friends: I am trying to find a widget or some other method to let me interrogate a 2-D image using the mouse. I have a data.frame that I can visualize using image() in R. I would like to point to a pixel and have its coordinates displayed. I've read Peter Dalgaard's primer on R-Tcl/Tk, R-News, 1(3):27-31, and his update R-News2(3):25-27, but am still struggling. Can anyone

Hi, We have a few R scripts, that have a minimalistic GUI Interface using winDialog() calls. Is there any cross-plattform equivalent we can port to, such that the code will run on both Windows and Unix ? I thought about either tcltk or gtk Stuff. I was astonished that I couldn't find anything similar that had been implemented since the 0.99 release, or do I miss something obvius ? Yours,

Dear List, I'm looking for some documentation about the R tcltk package The one I found in the help doesn't look exaustive, I need information on the use of the single tk widget, maybe with some examples thank you, simone gabbriellini

...sary. But I can't see what harm it could do... I am just wondering approximately how many people use / have used some of the R stuff I've developed (and in how many countries). In particular I'm talking about the R-Tcl/Tk examples I've put at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ and/or my two BioC packages limmaGUI and affylmGUI (now maintained by Keith Satterley), and/or the IBC2004 and JSM2005 microarray analysis course websites. If it's not too much trouble, could you please tell me [OFF THE LIST] if you use / have used any of these things (otherwise don't r...

Greetings: I would like to use tcl/tk with R, and have read "A Primer on the R-Tcl/Tk Package" by Peter Dalgaard in Rnews, Volume 1/3, September 2001. Are there more recent do-it-yourself instructions available? I have been unsuccessful with the example in the tcltk2 package due to a syntax error. I think that I have isolated the problem to this code snippet: for (i in
