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, I have the TCl/Tk command "tkmessageBox(titel="",message="x",icon="question",type="okcancel")" in my R script. Now I want to perform some operation in relation to the user's choice, something like "if (okpressed) xxx else yyy" What values does this command give and how are they used? Thank you, Richard -- Richard M?ller -

Hello, the admonition of Prof. Ripley to search the documentation to solve my problem helped, today I read a lot more on Tcl/Tk than before ;-) But now I'm stuck again. With the help of my script some functions are plotted on the display, then I ask if the user wants to save it as pdf. In windows I use winDialog and it works. But I can't succeed in Linux. In short:

I am using the following code but I do not know the debug and run for correct errors library (tcltk) file <-tclvalue (tkgetOpenFile ()) if (nchar (file)) { tkmessageBox ("Select the file") } else { tkmessageBox (message = paste ("Was select file", file)) Dataset <- read.table (file, header = FALSE, sep = "", na.strings =

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

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

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

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 List, I'm looking for some informations about the function "tkinsert()". I d'like to write lot of command in my text window and after to evaluate it with a button "Submit" for example, but i have some problems: here a exemple of my code: 1) My first problem tt=tktoplevel() txt=tktext(tt,height=40) tkpack(txt) var1=paste("x=2")

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 ...

I have just installed the latest version of R on a openSUSE 12.1 system running on an ORacle VM VirtualBox and have encountered a problem with installing ChemometricsWithR.

Dear R users graphing with plot(x) seams to work for a small length(x), when length(x) is too large it seams to clutter the display, a solution would be to display subsets of x at a time, yet a better way which I hope R supports is to place a sliding bar on the display window to control length(x) and thus the resolution, which will involve auto scaling the y axis as well as automatically

Hi, I am working under Windows and I am using R2.11 I want to use tkscale in my GUI. As the interval is quite big, I can't set the scale to a certain specific value.
