It seems that there are speed issues when printing to the R console from a tcl/tk GUI. Here are functions to write a lot of output, and to display how long it takes. printsalot <- function(n) { for(i in 1:n) cat(i, fill = TRUE) } timings <- function(n = 1e3) { print(system.time(printsalot(n))) } Calling timings() from the console reveals a run time of a few hundredths of a second.

Within a loop I tried to draw some things in dependency on the position of the mouse. This works fine with R-1.5.1 but R-1.6.1 requires to include some delay by Sys.sleep(delay) with delay>=0.015. For smaller values (e.g. 0.0001) the top level tcltk-window does not appear and so I am not able to control the elements to be plotted using the tcltk-widget. Question1: How can I force

Hi everybody, I have a problem with the grid function in tk. I juste try to put 4 buttons like this: ------------------- | | | | | C | | A |--------| | | | ---------- D | | | | | B | | ------------------- A is 2x2 C is 1x2 B is 1x2 D is 2x2 but the code bellow dont work : require(tcltk) tt <-

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,

Hi. I'm running into problems with using R functions as callback commands for buttons in Tk. The following Tcl/Tk script creates three buttons. If you press hello it prints hello world. If you press HALLO it prints HALLO WORLD. Not exciting, but I need an example... set tt [toplevel .tt] foreach i {"hello" "HALLO"} { pack [button $tt.b$i -text $i

Hi, I have a tktoplevel window and in it a tkbutton: AUS <- function() { foo(parameters); } AUSButton.but <- tkbutton(tt,text="OK",command=AUS) The function foo(...) does a time-consuming calculation, and during this calculation there is printed some progress information to the console. My problem: When I click the button "OK", the tktoplevel window and the R console

Hello, I am using R 2.11.1 under Windows XP. I would like to know if its possible to use a function with arguments as a command in tcl tk. For example require(tcltk) PressedOK <- function() { tkmessageBox(message="You pressed OK!") } tt <- tktoplevel() OK.but <- tkbutton(tt,text="OK",command=PressedOK) tkgrid(OK.but) tkfocus(tt) the function PressedOK has no

hello, i would like program userfriendly tcl/tk widgets like the t-test example in a more complex way ! (1) Is it not possible to combine tk_getOpenFile with the R function read.table to select in userfriendly way data sets ? (I'm newbie and take code-parts from t-test example and scripting example.) (2) Is it possible to use a variableSelection widget to select a special variable which i

Hello, I am sorry if this is an answered question, but I did my homework for a long while and couldn't figure out a way to retrieve data entry from a model dialog. In one of the examples compiled by James Wettenhall: odalDialog <- function(title, question, entryInit, entryWidth = 20, returnValOnCancel = "ID_CANCEL") { dlg <- tktoplevel() tkwm.deiconify(dlg)

Hello, I'm very new in working with tcl/tk in R and have a problem which will probably sound silly to most of you. Here is the code I have problems with: readcelfiles <- function() { require(tcltk) tt <- tktoplevel() tkgrid(tklabel(tt,text="Choose a directory!")) OnOK <- function() { fileDir<-tclvalue(tkchooseDirectory()) data.raw <-

Dear list members, I've been puzzling over how best to clean up the code for my Rcmdr package. In particular, there's a lot of repetitive tcltk code in the package, and as Martin M?chler has pointed out to me, this makes the package difficult to maintain. If R were Lisp, I'd use macros for much of the clean up. My efforts to do similar things with R functions has run into problems

Well the picture is pretty self descriptive [Image: http://img58.imageshack.us/img58/6315/screenshotwineconfiguraxo1.th.png ] (http://img58.imageshack.us/my.php?image=screenshotwineconfiguraxo1.png) For things like buttons, tabs, scrollbars, and toolbars the top right and bottom left pixel is inverted. There are more artifacts next to the scroll bar. I have tried it with and without Compiz and

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 <-

The following code should give me (at least that's what I think) two list boxes with their individual scrollbars. But instead both scrollbars stick to the same listbox even though they work as they should (scroll individual listboxes). When I remove all the widgets on top everything works perfectly. Any help would be highly apprecciated. ps: all subsequent listboxes and scrollbars work

This is my simple code, my intention is to let the inner function browse the objects in the outer function. ####################### tk1 <- function() { tk2 <- function() { inner <- 3 list2 <- ls() #list objects in fuction tk2 print("**** inner objects ****") print(list2) #list objects in fuction tk1 list_parent <- ls(parent.frame())

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause. Thanks very much, JeeBee. require(tcltk) || stop("Package tcltk is not available.") # Add path to

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
