Hi, I am having trouble debugging this one. The code is attached below, but it seems to be a problem at the C-tk interface. If I run this 1 time there are no problems if I run it more than once I start to get warnings that increase in multiples of 11 everytime I run it. Here is a sample session > source("clrramp2.r") Loading required package: tcltk Loading Tcl/Tk interface ... done

This makes scenarios like laptops with external monitors on Xrandr 1.2 work. Those e.g. have a 1280x800 output and a 1280x1024 output, completely overlapping each other. With this patch, outputDeviceForGeometry will return the smaller head for a rectangle that's completely inside the smaller head and the larger head otherwise. --- src/screen.c | 88

Hi! I've got two problems with listboxes and selection: I created a listbox, no problem. Then I bind the Button-1 of the mouse to the listbox to start some things by pressing the mousebutton. The proiblem is that as I click a item of the listbox this error occured: Error in .Tcl(.Tcl.args(...)) : [tcl] bad listbox index "": must be active, anchor, end, @x,y, or a number. Repaeting

Dear all; I would like to draw a graph with vertices and edges, and I guess tcl/tk would be appropriate. I don't know tcl/tk but have googled for a 10-page (or so) introduction to 'getting started with tcl/tk in R' but without any luck. - Does anyone know of the existence of such a document or any other web-based material on the subject? - Does anyone have an (informative) piece of

I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

Hi List, Can anyone tell me how could i put the "BACK" button in the following code, just under the "AAA" menu? I want this button to go back to the previous page, and since it has nothing to do with the "1" and "2" buttons, i want it somehow separated from these two buttons, but i don't know how. I searched the web for some examples but my results

Dear gurus: I have a question on how to configure the margin layout on tcl/tk GUI objects like tkcanvas, tkframe or tktoplevel. For example, if I want to leave a larger margin on the left side of the GUI container, which one should I configure, the toplevel or tkcanvas or tkframe? top<-tktoplevel() canvas<-tkcanvas(top, relief=, borderwidth=...) I also find the documentation for all

Hello, I've built the package distr (see link below) successfully with R 1.8.1 and R 1.9.0 beta (under Linux). As to make the package compatible to R 1.8.1 / 1.9.0, I have to use two different NAMESPACE files. For 1.8.1 it has to contain import("methods") import("stepfun") and for 1.9.0 the "import"-part has to be import("methods")

I have two packages, one that does the actual work (SC) and the other a Tcl/Tk UI (SCUI) that invokes methods within the former. Within the SCUI's invocation method, I save an object returned from SC, the results of a long-running method. Now the object is completely described by the SC package. Unfortunately, any attempt to load the object (in a fresh R session) fails as below. R>

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

To represent a turtle inside a canvas (tcltk package), I have a serie of bitmaps representing the turtle heading in different directions and I would like to display the one that corresponds to the current direction of the turtle (function below). I have created with Paint a bitmap representing the turtle in BMP format and succeeded displaying it on canvas after converting it into XBM format

Hi, I think that R-tcltk doesn't have the capacity to display an image stored in memory on a tkcanvas object, am I right? I have digged around everything I can find from Peter Dalgaard and tcltk references and drew my conclusion. Can you, Peter, or some other gurus on the list, give us a pointer or two on how to proceed to solve this problem? I am afraid that it may involve writing C

Hey all, I get the following error. Now I know it''s related to a curly brace, but it seems that all curly braces are properly in place. So I''m not sure why I get this error: SyntaxError in DashboardController#panels rails/app/controllers/dashboard_controller.rb:170: syntax error, unexpected ''\n'', expecting tASSOC def panels addDetailToContainer =

'tkcoords' is defined twice (in the same way) in src/library/tcltk/R/Tk.R. Attached is a patch against r63780 that removes the duplicate definition and alphabetizes the functions. I've read that minor patches such as this should be sent to r-devel [1]. Scott [1] http://permalink.gmane.org/gmane.comp.lang.r.devel/33987 -- Scott Kostyshak Economics PhD Candidate Princeton

I'm trying to build up a user inteface using the R tcltk component. Since the documentation for this R library is scarce and poor, I have decided to use only the .Tcl function to pass commands to the tcl interpreter. So I wrote my first very simple tcltk program, hoping to run it from inside R and get the nice Tk window, with the following R instruction: -> .Tcl('source
