Why the variable archOp does not take the value that be chosen in the menubutton?, therefore always remains as a white one, I intend to charge the direccion of open files in a vector and then to elect with the menubutton with which to work but not functions thanks.Ruben library(tcltk) arch<-tclVar(init=" ") archOp<-tclVar(init=" ") vectPath<-c()

hello, how i cant to charge in form dynamic a checkbutton, try to do it with a vector be charged automaticamente but not works, for example library(tcltk) tt<-tktoplevel() f<-tkframe(tt) tkpack(f) i<-2 if (i==1) {b1<-tkcheckbutton (f,text="b1",variable="b1",relief="raised");tkpack(b1);print(tclvalue ("b1"))}else if (i==2) {b1<-tkcheckbutton

Hi again R People: This works fine: > library(tcltk) > a <- tclVar("4.5") > as.numeric(tclvalue(a)) [1] 4.5 > #But if you have: > b <- tclVar("pi") > as.numeric(tclvalue(b)) [1] NA Warning message: NAs introduced by coercion > Is anyone aware of a way around this, please? thanks, Erin -- Erin Hodgess Associate Professor Department of Computer

Hi everyone, I have a problem to assign a value with tcl/tk ths is the code ( it should be simple to understand) : library(tcltk) valA<-tclVar("0") valB<-tclVar("0") valC<-tclVar("0") id<-"A" out<-"1" out2<-"2" print(paste("tclvalue(val",id,")",sep="")) # ok

Hi All... In an attempt to read data from a file and feed it into a tcltk entry box, I've run into difficulties. The following hopefully describes my dilemma: tclvalue(x.var) <- 5 Works fine. tclvalue("x.var") <- 5 Does not work. [Error: Target of assignment expands to non-language object] tclvalue(eval(parse(text="x.var"))) <- 5 Also, does not work. Any

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

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 ...

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

Sorry, my question is if exists a command tkexit in R, i need a command how exit of tcl for close an aplication. How to use him. Thank

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, 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

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 (

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 <-

Dear R-users, I would like to build N "tkentry" compounds in the same window, with default text for each. As N is variable I need to construct them in an iterative way : library(tcltk) main<-tktoplevel() tktitle(main)<-"My Tool" filenames<-c("toto","tata","titi") N<-length(filenames) for (i in 1: N) {

Hi, I have a large plot that I would like to display in a graphics device with scroll bars. I therefore decided to use the windows function like so... mag<- length(tick) windows(height=mag/8, width=10, rescale="fixed") However, when I use the scroll bars the device (i guess) is re-drawing the plot. Is there any way in which I can get it to 'smooth scroll'? Kind regards,

Dear R users, I have some troubles with dealing with tclObj objects. I try to explain it with a toy example: Say I define the following tcl procedure which just prints out each list element library(tcltk) .Tcl('proc test {myList} { foreach i $myList { puts stdout $i } }') and I call it with: > tcl('test',letters[1:5]) # Works as expected Now say I define
