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

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

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.

Hello everyone, this is my first post here and I hope I signed up correctly and someone will take me by the hand and help me out. I am new to R and cannot figure out what to do here... ... I want to have an User Interface that requests input. I want to save this input to a variable to use it later on. I was able to do this with a modalDiaglog (

I searched the web and the list archives for a solution to this, but didn't see anything, so here goes. I'm new to tcltk. I'm trying to change the contents of a tkentry widget when a button is pressed. Once I get that working, the widget will be read only to the user. Here is some toy code: ############### require(tcltk) thisEnv=environment() tt<-tktoplevel() Name <-

Hello, I am trying to write a tcltk based program that plots/manipulates xts/xoo time series objects. I have the code I used from ## http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tkrplot.html : ## require(quantmod) require(tcltk) library(tkrplot) Sys.setenv(TZ="GMT") getSymbols("^GSPC", from = "1960-01-01") Myhscale <- 2.5 # Horizontal scaling

I would like to use a tclArray: mytkarray <- tclArray() as the variable for a table: table1 <- tkwidget(f1, 'table', 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

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,

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

Dear R Gurus: What is the name of the person who has all of the Tcl/tk stuff, please? I know it's James W, but can't remember his last name. I wanted to look at some of his examples.

Hi - I'm creating a package of database tools. A function in the package requires the username and password as input to the function in order to initially connect to the target database(s). Of course, this poses a significant security issue given the possible retention of the function statement in cleartext. I did not readily encounter a package meant to mask input from the user nor do I
