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...

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?

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()...

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,

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. Jeff

Hi, I see in Wettenhall RTclTk Examples that tkbind(xxx, <Key>,...) can pass the key pressed. How can I get the key pressed? Thanks, Manel

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

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

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.
