I think I - almost - got the knack for GUI programming using the tcltk library. Maybe I will update the RWiki with this: # ################################################# # library(tcltk) # # Create some matrix - nothing about tcltk here # matrix <- cbind(rnorm(100), rpois(100, lambda=10), runif(100), rt(100, df=2), rt(100, df=4)) colnames(matrix) <- c("Normal",

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 Rodrigo, Try tkwm.geometry(win1, "-0+0"), which should position win1 at the top right.

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 <-

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')

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)

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

Hi everybody, I am trying to write a simple progress display based on a tcltk toplevel. My first approach was to use the progressBar widget from the BWidget library but since this is not available on every system (missing on at least almost all windows systems, I guess...) I wanted to have a backup there. So my second strategy was to use a simple toplevel with a label and update the tclvariable

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

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

Hi thank you for talking the time to help me with this. I have a sequence of numbers in a file and an equal sequence of various character, say(a b c d) each occurs more than once. I need to plot the numbers so that numbers corresponding to a in the other sequence would have green dots, those corresponding to b a red dot, nothing on c and blue square for d. i.e 2 a show a green dot 4 b show a

Hello, On Mac OS X, certain Aqua/Quartz UI functionality requires an application to be launched from within an app bundle, or (alternatively) requires a Carbon application with a resource fork. Playing with the wxWidgets distribution, I discovered that it is quite easy and transparent to make such a Carbon app from (I guess) any command line application. When applied to the R executable called

I can set up an entry widget (thanks to an old post by Barry Rowlingson) that gets a password and exits when the user clicks on the "OK" button. Anyone have any clever ideas for returning/ destroying the window when the user types a carriage return/ENTER in the text window? I've messed around a little with validate, validatecommand, but don't see any obvious way to do it ...

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 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

hello list, Can someone help me figure out why the following code doesn't work? I'm trying to but both Greek letters and subscripts into a tcltk menu. The code creates all the mu's, and the 1 and 2 subscripts, but it won't create the 0. Is there a certain set of characters that R won't recognize the unicode for? Or am I input the \u2080 incorrectly? library(tcltk) m

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 <-

Hallo, I'm dynamically generating buttons depending on the number of rows of my dataframe. Every button is supposed to call a function which generates a plot with the values of one of my dataframe rows. My code looks like this: base <- tktoplevel() plotten <- function(mat, namen, titel) { midpts <- barplot(height=mat, names.arg = namen, main = titel, las=2)
