Hi, is it possible to put a summary of an rpart-Object into a tktext-window? Here is what I'm trying to do: fit <- rpart(Kyphosis ~ Age + Number + Start, data=kyphosis) tt <- tktoplevel() tex <- tktext(tt) tkpack(tex) tkinsert(tex, "end", summary(fit)) But since the summary of an object is a list, I always get back the following error-message: cannot handle object of

Hi, All, I'm writing a wrapper for stop that produces a popup window using tcltk. Something like: error <- function(...) { msg <- paste(..., sep = "") if(!length(msg)) msg <- "" if(require(tcltk, quiet = TRUE)) { tt <- tktoplevel() tkwm.title(tt, "Error") tkmsg <- tktext(tt, bg = "white") tkinsert(tkmsg,

Dear list members, Rich Heiberger reported to me last week that the Messages window in the Rcmdr GUI was freezing -- that is, messages posted to this window didn't appear -- under Windows and R 2.8.0. I was able to confirm this problem on three Windows systems, one using Vista and the other two XP. In each case, I used R 2.8.0 and Rcmdr 1.4-4 (the current version). The problem doesn't

Hi; I have a program which writes lines to a tktext box (of height, say, 10) with tkinsert(txto, "end", paste(so,"\n")) I would like my program to be such that it automatically scrolls down through the text box when it is full so that I always see the last 10 lines written. Can anyone help on this? Best regards S??ren

Hello I have been playing with tcl/tk in R 2.4.0 on windows XP and have managed to crash R by supplying tcl/tk with an incorrect color. Is this a bug? is there a way for me to test the color to see if it is a valid tcl/tk color, to avoid this? tt=tktoplevel() tklabel(parent=tt, text="hello world", foreground="reed") Error in structure(.External("dotTclObjv", objv,

Hi there, a text Window is supposed to map the shortcuts for copying and pasting (<Ctrl-C>, <Ctrl-V>) automatically. I'm working under Mac OS X and my text window doesn't really map these functions automatically - it works fine under Windows. Is there an easy way to map copy&paste functions to a text window under Mac OS X? This is what I'm doing with my text

Hi all, Roger Peng and Jason Turner's suggestion with ImageMagick seem to be the simplest "dirty" way to get the problem solved. But I ran into yet another interesting but quite round-about way to solve the problem (partially). Through tcltk package, one can read in the gif image with > x <- tkcmd("image", "create", "photo", file=mypic.gif)

Sorry, for my mail from last night contains no subject. Therefore, I send it again and two tcltk questions are appended. ---------------------------------------------------------------------------- Prasad wrote: > I wrote a function in R which uses tcltk package .... essentially I wanted > to give within that function, a widget with 2 radiobuttons to choose > between plotting Precip

I don't know whether this is specific to (my installation of) SUSE 10.1, or is more general. With R 2.6.0, I am finding that some widgets made through the tcltk package are having problems which become evident through scrollbar activity. An example is demo(tkfaq) -- see below. To reproduce the problem, I do the following: after the tk window appears, hold down the

Dear all, please excuse the somewhat special question: >From within R I create a Tk windows with a list of checkboxes, which can bekome too long for the screen. The obvious solution would be to put all checkboxes into a frame and make that scrollable. Alas, there are (for whatever reason!) no scrollable frames in Tk :-( The usual workaround is to put widgets (my checkboxes) into a textbox,

I've been able to figure out on my own how to do what I need in the largely undocumented tcltk package, but I've finally hit a wall. I can't even think of any sufficiently specific search terms to use for this. I'm trying to make the widgets in my tk window resize when the window is resized by clicking and dragging on its corners or edges. Instead they stay exactly where they

Hola a todos, me gustaría saber si hay alguna forma de hacer que los mensajes que se muestran en la ventana de comandos de R se muestren en una interfaz en tcl tk. Me gustaría modificar la salida del comando cat y que se muestre tanto en la ventana de comandos R, como en una variable de tipo tktext dentro de la interfaz. Muchas gracias.

Dear list members, Is it possible via a suitable tcltk command to get the *current* width, in characters, of a Tk text widget that has been resized with the mouse? In the following code, the reported width of the text widget doesn't change, even though it has been resized. I can, however, get the current width in pixels: > library(tcltk) > top <- tktoplevel() > textWindow <-

Dear List, I'm looking for some informations about the function "tkinsert()". I d'like to write lot of command in my text window and after to evaluate it with a button "Submit" for example, but i have some problems: here a exemple of my code: 1) My first problem tt=tktoplevel() txt=tktext(tt,height=40) tkpack(txt) var1=paste("x=2")

Can anyone show me how to connect a scrollbar to a text widget using the tcltk library? I'm confused about how to make sure the two widgets know about each other and how to set up the appropriate call-backs for scrolling.

I like to monitor simulation by reporting some current values to the console, every 25th iteration say. I think it might be nice to have that appear in a separate window. Anyone know how? regards, David Farrar New River Analytic [[alternative HTML version deleted]]

  Hi all. I'm having a little trouble with the  function "texteval" (session package). I have used "texteval" in the construction of the function "ExpandData1". "ExpandData1" does not work as expected. However, when I run only the inside code of "ExpandData1" I get the right result. Apparently "texteval" is not working when used

Hello, I'm using R 2.0.0 with the latest Rcmdr package installed from CRAN, on Windows XP Professional. When trying to copy some commands or results, either from the upper or lower text window, this causes Rcmdr to crash: "R for Windows GUI front-end has encountered a problem and needs to close" Did anyone have the same problem? I don't think it's my system, as it
