Hello, I am sorry if this is an answered question, but I did my homework for a long while and couldn't figure out a way to retrieve data entry from a model dialog. In one of the examples compiled by James Wettenhall: odalDialog <- function(title, question, entryInit, entryWidth = 20, returnValOnCancel = "ID_CANCEL") { dlg <- tktoplevel() tkwm.deiconify(dlg)

Hello! I want to create a messagebox whenever the user wants to destroy the window (e.g. <Alt-F4> or the 'x' in the right top corner) and ask if a modified file should be saved or not. If 'cancel' is chosen then nothing should happen and the windows still should be existing. This doesn't work. When I press cancel the window will be destroyed although. I also

Hello, I am using R 2.11.1 under Windows XP. I would like to know if its possible to use a function with arguments as a command in tcl tk. For example require(tcltk) PressedOK <- function() { tkmessageBox(message="You pressed OK!") } tt <- tktoplevel() OK.but <- tkbutton(tt,text="OK",command=PressedOK) tkgrid(OK.but) tkfocus(tt) the function PressedOK has no

Dear all, I'm trying to use tcltk to build a small user-interface and couter the problem: It seems that sometimes the dialog box will be minimized automatically though I want it to be on top of the screen all the time. For example, when runing the following code, if you type in "a1", "a2", "a3", etc when being asked for an integer, the program is supposed to

--0016e6d464cff5d753047d482362 Content-Type: text/plain; charset=UTF-8 I am experiencing some regular crashes on Debian Linux, 32- and 64-bit, involving 'tcltk' and 'cairoDevice' or 'RGtk2'. They make it very difficult to use tcltk interfaces (Rcmdr) and GTK+ ones (rattle, playwith, etc.) in the same R session. NOTE: Before you continue, please read NOTE2 located towards

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 -

Hi Sorry, my first post was in German. I tried to get Rcmdr running under MacOS X 10.4.5. While RGui pretends that tcltk is running, starting Rcmdr freezes R completely. Instead, JGR which gave me the following results: > library(tcltk) Loading Tcl/Tk interface ... Error in fun(...) : no display name and no $DISPLAY environment variable Error: .onLoad failed in 'loadNamespace' for

I have JUST started using R. I am using R 2.0.1 on a mac (os x) to run another program (called GRASPER, Generalized Regression Analysis and Spatial Prediction for R).

Hello everyone, i have been searching the whole day, trying ANY solution offered by the internet and before headbanging against the wall would like to try asking for your help. As many others, i am haveing problems loading the Rcmdr package with Macbook running Tiger 10.4.11. X11 version updated to the last one after having manually installed.

Greetings. Yesterday I decided to try out Rcmdr, but it refused to load. I traced the problem to the library tcltk, which when I tried to load it told me this: > > library(tcltk) > Loading Tcl/Tk interface ... Error in fun(...) : > Can't find a usable init.tcl in the following directories: > @TCL_IN_FRAMEWORK@ @TCL_IN_FRAMEWORK@ > > > > This probably

Hallo ! Ich habe versucht Rcmdr unter MacOSX 10.4.5 zu installieren. RGui zeigt an, dass tcl/tk laufen. Bei Aufruf von Rcmdr friert R jedoch komplett ein. JGR zeigt im Paketmanager dagegen an, dass tcl/tk nicht gestartet werden konnte und spuckt folgende Meldung aus: > library(tcltk) Loading Tcl/Tk interface ... Error in fun(...) : no display name and no $DISPLAY environment variable

Dear r-helpers, I wonder if you can figure out why the following is working: ******************************************************************** > sessionInfo() Version 2.3.1 (2006-06-01) powerpc-apple-darwin8.6.0 attached base packages: [1] "tcltk" "methods" "stats" "graphics" "grDevices" "utils"

Hello, Up to R 2.6.2, I used to start Tcl *without Tk* (I need only Tcl for some part of my work, like a socket server written in Tcl only, for instance) with this code under Mac OS X (particularly on this system, because I don't want to start X11 just to use Tcl code, which is required for Tk!): > Sys.unsetenv("DISPLAY") > library(tcltk) I got then the message

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

Hi, Recently, I've been trying to use packages in R that require loading the Tcl/Tk interface. However, I get a strange result and a crash that I haven't been able to find discussion about on these boards (or any others). When I enter library(tcltk), it reads "Loading Tcl/Tk interface ... ", but then never says "done" or displays some sort of error message. Looks
