Using Tk table widget to display matrix
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.

Changing text in a tkentry widget
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 <-

Dropdown boxes in tcltk and R
Hello, I'm very much a newbie in R and more so in tcltk so apologies if this question is stupid. Basically I am trying to use the combobox example found here: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html . What I want to do is in that example get fruitChoice as a variable in R in general. When I run that code, however, and the ask for fruitChoice it says

R TclTk Examples
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

Offline ? Searching for James Wettenhall's TclTk Examples
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

locator() via tcltk
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

Output from function to a tcltk window

tclarray with embedded spaces in data
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

Corrupt trees
Hi Everyone, I have been using the "tree" package for a while with no problems until now. When I run predict(tree, newdata), I get an error with the message "Corrupt tree" for about 50% of the trees that I generate with tree. For other trees, the predict function completes with no errors. I haven't identified a correlation between the corrupt trees and the working tree.

tree/graph data structure APIs?
What is the best code available for simple general purpose manipulation of tree (and/or directed graph) data structures in R? Looking through CRAN, I see a bunch of packages for stastical regression trees, but nothing that seems to provide an API for manipulating tree data structures. What I'm looking for is something along the lines of an R version of the Tcllib ::struct::tree API available

Adding Tk extensions to R for windows
Hi, I'm developing an R/TclTk application which uses the BWidget and Tktable Tk extensions and I'm trying to make it easy to install. For now, I'm focusing on Windows users who start with nothing. I have built Tcl/Tk and Tktable for windows using Msys/MinGW. (BWidget contains only Tcl scripts so does not need building.) I have then copied Tktable and BWidget into the lib subdirectory

Classification trees and written conditions
Dear All When drawing a classification tree with plot(mytree) text(mytree) the conditions are written just before the nodes branch. My question is: can one be certain that those conditions refer to the left-side branches? (The R documentation surprisingly lacks the information that I am asking for.) Thanks in advance, Paul

problem in labeling the nodes of tree drawn by rpart
Hi all, I used rpart to fit a model, where the covariates in the model are categorical variables. Then I plotted the tree (mytree) and used the command "text" to add labels to the tree. In the nodes of the tree, the values of the covariates are represented with a, b or c. Is there a way to show the real value(s) of the variable in the nodes instead of a, b or c ? I found that the

Request for users of my R-Tcl/Tk examples, limmaGUI or affylmGUI
[PLEASE REPLY _OFF_ THE LIST, i.e. DON'T CC to r-help at ...] Hi, I don't see this sort of thing very often on the mailing lists, so list moderators and others should feel free to tell me if it breaches list etiquette and/or delete my post if necessary. 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
