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())

Greetings: I wish to use a tcl/tk widget to ask for user-selected parameter values. My widget works ? it asks for and returns to my workspace the stuff I need. Here is a snippet of my code: ############################### OnOK <- function() { LOG.X <<- as.logical(as.character(tclvalue(log.X.buttonValue))) LOG.Y <<- as.logical(as.character(tclvalue(log.Y.buttonValue)))

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,

Full_Name: Robert King Version: 2.1.1 OS: Linux (debian stable, with backport R) Submission from: (NULL) (142.58.147.28) update.packages documentation (and code, from what I can make out) says: ask: logical indicating whether to ask user before packages are actually downloaded and installed, or the character string '"graphics"', which brings up a

Hi, I have two questions: First, does anyone know how to put a combobox inside a GUI made with Tcl/Tk ? I think there isn't a simple way to do this (a command like tkcombobox()!), but is it possible to write a more complex code to achieve this ? Second, when I put two listboxes in the same window or frame (even in two different toplevel windows), I cannot select things in the two lists

Hi, I've been playing with the tcltk package. It's very nice to have access to buttons, menus etc. now. Thank you! Alas, I also have questions: In Tcl everything is a string [*]. This is not the case in R, of course. So why are return values of tk commands still strings? (Is there any other reason than speed or "package is work in progress"?) Example: > tt <-

Dear R People: This is more of an opinion question please: When putting together GUI type functions, is it better to use JAVA or Tcl/Tk, please? Any input is appreciated!

Hi I've a problem with the following example: library(tcltk) .Tcl("array unset tclArray") myRarray <- matrix(1:1000, ncol=20) for (i in (0:49)) for (j in (0:19)) .Tcl(paste("set tclArray(",i,",",j,") ",myRarray[i+1,j+1],sep="")) tt<-tktoplevel() table1 <- tkwidget(tt,"table",variable="tclArray",

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 <-

Friends: I am a long-time R user, learning tcl/tk, and am tying myself in knots over something that should be simple. I want to create a frame and put that frame inside the toplevel frame. This works (i.e. it places text in col 1, and the corresponding entry box in column 2) and later frame.2 resides where it should in the toplevel frame. tkgrid(tklabel(frame.2, text="FACTOR column

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 <-

hi, just having the idea create a simple tcl/tk gui-dialog for different data-file formats i get starting problems and it would be nice get some tips/tricks from experienced tcl/tk user in R ! tt <- tktoplevel() label.widget <- tklabel(tt,text="Decision Tree GUI") button.widget <- tkbutton(tt,text="Select SPSSFile", command=function()

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. Jeff

'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

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

I'm working on a matrix editor using the Tk table widget, and it is almost done. It slices, dices, etc., and it can paste into Excel from an R session running on Linux. What I don't know how to do is paste from Excel into a Tk table, and Google is not helping me. Can anyone lend me a clue? Jeff

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

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

Dear R-devel: Would R core team consider endorsing a graphical toolkit and trying to facilitate development of little GUI tools? I need a gui matrix editor for users that want to be able to write matrices that are later used to simulate data. Instead of teaching them to write a covariance matrix (for example, for mvtnorm), I want to tell them run a function that pops up a table they can fill

I'm trying to use a Tk widget to show some progress & intermediate results in a long-running R calculation. Does anybody know how (or whether) I can force a window redraw without waiting for the idle loop? Currently, refreshes only seem to happen when we return to the R toplevel read-eval-print loop.
