Hello companions!!! I have a function that creates a Radio Buttons, and I need that this function return the selected value in the Radio Buttons. I would like that, if somebody know as I could return the value, you say me as do it. Next, I show the function function1<-function(){ require(tcltk) tt <- tktoplevel() rb1 <- tkradiobutton(tt) rb2 <- tkradiobutton(tt) rbValue <-

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

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 <-

Hello, I'm very much a newbie in R and more so in tcltk so apologies if this question is stupid. Basically I am trying to use the combobox example found here: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html . What I want to do is in that example get fruitChoice as a variable in R in general. When I run that code, however, and the ask for fruitChoice it says

Hello, I am trying to write a tcltk based program that plots/manipulates xts/xoo time series objects. I have the code I used from ## http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tkrplot.html : ## require(quantmod) require(tcltk) library(tkrplot) Sys.setenv(TZ="GMT") getSymbols("^GSPC", from = "1960-01-01") Myhscale <- 2.5 # Horizontal scaling

Hello everyone, this is my first post here and I hope I signed up correctly and someone will take me by the hand and help me out. I am new to R and cannot figure out what to do here... ... I want to have an User Interface that requests input. I want to save this input to a variable to use it later on. I was able to do this with a modalDiaglog (

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 am trying to insert a jpeg into a widget I have created. I have used this link http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/showImage.html to display a jpeg inside a newly created widget but would like some info on how to insert into a pre existing widget. This is my code below for my first widget. tt<-tktoplevel() fontHeading2 <-

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've been learning how to use R TclTk in Windows over the last few months. I have recently put together a collection of examples of some common widgets and their corresponding R code, at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ I would be interested in any feedback - Is it useful? Does it contain any significant errors or bad coding style? Does anyone else want to

Thanks everybody for looking at this. I am trying to assign a script to a button please help: ############ library(tcltk) tt<- tktoplevel() tktitle(tt)<-"the title" heading<-tklabel(tt,text="Enter date as YYYY-MM-DD") l1<-tklabel(tt,text="Reporting date") b1=tkbutton(tt,text="Run") d.val<-tkentry(tt,width=12) tkgrid(heading,columnspan=2)

Hi - I'm creating a package of database tools. A function in the package requires the username and password as input to the function in order to initially connect to the target database(s). Of course, this poses a significant security issue given the possible retention of the function statement in cleartext. I did not readily encounter a package meant to mask input from the user nor do I

Hello, everyone. I have the following problem with TclTk: I create some windows and want to change their position with geometry manage (sometimes they will be centered, sometimes not). If the toplevel is created and its dimensions are gathered via 'tkwinfo', I get (usually) correct values. However, if this window is created by a function (in the following example, by 'ask.format')

Hi, as a starting point for using Tcl/Tk in R, I used to refer to James Wettenhall's nicely presented TclTk Examples formerly hosted at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ These days I have been trying to reach these pages but without success. Does anyone know (James, himself, perhaps ;-) whether they are / will be available at some other location --- it would be a pity

I would like to display output to a tcltk window from e.g. a call to summary(). I tried to get something else than oneliners into a text window of the kind found at: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/TextWindows.html But without success.

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

I'm trying to create an app using TclTk and R Can someone please explain how I bind a click event to the tree widget (http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/TreeWidget.html) Ideally I'd like to bind to particular elements in the tree but tkbind doesnt seem to work. thanks tom

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

I would like to use a tclArray: mytkarray <- tclArray() as the variable for a table: table1 <- tkwidget(f1, 'table', variable= mytkarray) but if I include character strings with embedded spaces, I get braces appearing in the table. I can remove them using a non-R tclarray, (the difference between the first example of http://www.sciviews.org/_rgui/tcltk/Tktable.html and

Hello, I'm trying to write a function using tcltk to interactively modify a plot and gather locator() data. I've read Peter's articles in Rnews, the help pages in tcltk, http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/, plus a post in R-help sometime ago, but haven't found a solution. The idea goes something like this: require(tcltk) testplot <- function() { getcoords
