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

Hello, I have a problem with a tklistbox. The user should be able to choose one out of two calculation methods needed for further calculations. My r-script for that purpose looks like that: require(tcltk) tt<-tktoplevel() tl<-tklistbox(tt,height=4,selectmode="single",background="white") tkgrid(tklabel(tt,text="select method for LAI

Dear experts, I am trying to understand why is it that when I paste (into the R console) the following code to select an option from a list: require(tcltk) tt<-tktoplevel() tl<-tklistbox(tt,height=ntx,selectmode="single",background="white") tkgrid(tklabel(tt,text="Select the legend of" )) tkgrid(tl) treatments<<-levels.tx for(i in

Hello all, I've had trouble converting a data.frame to a matrix (numeric) using either data.matrix() and as.matrix(). After executing one of those I end up with another data.frame with only the first column of the original data.frame. I use a window (tcltk) to let the user choose the columns he wants and then I retrieve them using the following: varstemp <-

I don't know if this is a bug. I can reproduce the following on Ubuntu 12.04.2 and 13.04 64-bit with R version 3.0.1 and with r63479. There is no difference if R is patched with the fix for PR#15407 or not, although without the fix there are more ways to trigger this. I can reproduce with the following: 1. Open R in gnome-terminal or xterm 2. Run 'library(tcltk)' 3. Run

How can i replicate this in Linux: source(file.choose()) I've tried source(tkgetOpenFile()) but with no luck

Dear list, I have multiple (BWidget) listboxes in the same toplevel window. The problem is, if I select (by left clicking) on one of those listbox elements, the current selection in the *other* listboxes is cleared! Anybody knows how I can prevent this? Here's my code (sorry not complete): (E.g. If I select an X value, I'd lose the Y value I selected before) gui.create.tab.general <-

Dear r-devel list members, I've experienced the following problem in getting a selection from a Tk list box using tcltk. This is a long-standing problem, but I've finally decided to tackle it. Consider the following: Library(tcltk) top <- tktoplevel() listbox <- tklistbox(top, height="10", width="2", exportselection="FALSE",

Hey folks, This is my first message to the mailing list so please let me know if I mess something up. I'm trying to use the selectcommand for the mclistbox but I'm not very adept at using functions. Ideally I'd like to change the editor text when a different list item is selected but any help using the selectcommand would be appreciated and I think I could get the rest working.

Dear R-devel list members, I've encountered a problem with my Rcmdr package under Windows XP and could use some advice: The Rcmdr package uses the tcltk package to create menus and dialog boxes. My standard procedure when a dialog is created is to grab the focus -- e.g., by tkfocus(top) tkgrab(top) (Here, top is a top-level window -- say, containing one or more scrollbars.)

Hello, i'm trying to translate following tcltk source code, which I found in newsgroup comp.lang.tcl, written by Tom Wilkason, into R Code. proc scrolled_Canvas {base} { frame $base.fm -borderwidth 2 -relief sunken canvas $base.fm.cv -yscrollcommand "$base.fm.cv_vertscrollbar set" scrollbar $base.fm.cv_vertscrollbar -orient vertical \ -command "$base.fm.cv

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)

Turns out I needed to add "exportselection=0". So: foo.lb <- tklistbox(root, height = 5, selectmode = "extended", exportselection = 0) Got this from: http://tolstoy.newcastle.edu.au/R/e2/help/06/12/6955.html (That's what I get for assuming there'd be no tcl/tk questions on this list. D'oh!) Cheers! Mark -- I'm taking reality in

My laboratory is measuring the abundance of various proteins in the blood from either healthy individuals or from individuals with various diseases. I would like to determine which proteins, if any, have significantly different abundances between the healthy and diseased individuals. Currently, one of my colleagues is performing an ANOVA on each protein with MS Excel. I would like to analyze

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

I everyone, i have a little problem with tklistbox,the " " character and Rcmdr. Please look at this code require(tcltk) tt<-tktoplevel() levels.list2 <-tklistbox(tt,selectmode="multiple",exportselection="FALSE", height=4, yscrollcommand=function(...)tkset(levels.list2.scroll,...))

Hi, I would like to be able to dynamically (without reloading the page) change the values from one listbox when a user select items from another listbox. I have a model ''Sector'' which has_many ''levels'' (and of cours, ''Level'' beyong_to ''sector''). I want to show the user two listboxes with the sectors and levels. But
