Hi, I saved an image and planed to open it whenever I want to load it. However, when I open it, It doesn't work. The code is following, and saved it as an image. .First<-function(){ require(tcltk) require(TeachingDemos) library(gWidgetstcltk) options(guiToolkit = "tcltk") win <- gwindow("Don't worry", visible = FALSE) } Error message is following, Error :

I know almost nothing about the tcltk library, and the documentation seems very poor. What's the meaning of this error, and is there any way to fix it? I'm running R 2.4.1 in a Windows XP machine where I have almost no privileges (but at home I am the Evil Overlord of a Linux machine...) library(tcltk) tclRequire("Tktable") # [1] FALSE # Warning message: # Tcl package

Hi, I have successfully installed R 1.7.0 and ActiveTcl 8.4.2.0 in Windows 2000. Yes, I know that Tcl is already bundled with R 1.7.0, but I want to use the iwidgets package to create a drop-down listbox, and I don't think iwidgets is included in the bundled R 1.7.0/TclTk installation package. I have set the environment variables TCL_LIBRARY and MY_TCLTK to the directory where I

Hello; Well, I'm afraid this is the second related problem I report in two days (I'm sorry for this) I've programmed a tcltk interface for a model and it includes a comboBox. The comboBox widget comes with the "BWidgets" library of Tcl/Tk. It works all perfectly with the windows R GUI (with the help of Prof. B. Ripley), following the advices in ?Startup, but I would like

Hello, I have a problem with using Iwidgets in R while i'm able to use BWiget and Tktable. If I let tcl list the names of packages, Iwidgets seems available. I use R 2.6.0; in addition addTclPath("C:/Tcl/lib") has been used (in which iwidets is present) > try(tcl("package", "names")) <Tcl> http opt tcltest ::Utility::expand Widget ::Utility::number

...t;-tktoplevel() combo <- tkwidget(tt,"iwidgets::combobox") tkpack(combo) ### AND THIS WORKS TOO !!! ### tt<-tktoplevel() win <- .Tk.subwin(tt) .Tcl(paste("iwidgets::combobox",.Tk.ID(win),.Tcl.args())) tkpack(win) But they both fail in my old R session - maybe I've tclRequired another package or loaded another package which is interfering or maybe a Tcl object hasn't been cleaned from memory properly.

Hello, I am exploring the TCLTK package under R and try to load and use additional TCL libraries (under Windows, with TCL8.3). For example : > addTclPath("C:/TCL/lib/bwidget1.5") > tclRequire("BWidget") <Tcl> 1.5 Loading seems to work, but when I try to create a specific widget : # The main window appears correctly > top=tktoplevel() # Trying to insert a

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'm trying to use R to take an image matrix and paint it into a tcltk canvas. I'm using R-1.9.0 within ess-5.2.0 on a linux machine running the 2.4.30-31.9smp kernel.

Hi all, I just installed R on my Mac OS X machine and wanted to installed tcl/tk. So, I installed tcl/tk from this page: http://cran.r-project.org/bin/macosx/tools/ It gets placed in /usr/local dir. and then I installed R. Next, in R, I set the TCL_LIBRARY variable by saying Sys.setenv(TCL_LIBRARY="/usr/local/lib/tcl8.5") and Sys.setenv(TK_LIBRARY="/usr/local/lib/tk8.5") But

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

Hi I've a problem with the following example: library(tcltk) .Tcl("array unset tclArray") myRarray <- matrix(1:1000, ncol=20) for (i in (0:49)) for (j in (0:19)) .Tcl(paste("set tclArray(",i,",",j,") ",myRarray[i+1,j+1],sep="")) tt<-tktoplevel() table1 <- tkwidget(tt,"table",variable="tclArray",

Dear Rxperts.. I am trying to install a few packages in R (version 2.14.2) on a *64-bit Window 7* workstation. Some of the errors are posted below..

Dear R Helpers, Does anyone know how to use tcltk to display jpeg images? The manual says that one must use Tk_PhotoCreateImageFormat to register the jpeg image handler. The "ActiveTcl User Guide" (http://support.serv.ch/lang/tcl/img/doc/img-jpeg.html) says:- "The package img::jpeg is a sub-package of Img. It can be loaded as a part of the complete Img support, via package require

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags?

Hello! The IWigdets::combobox has an option "selectioncommand" to specify a procedure which is called when an item in the combobox is selected. Does ComboBox from Bwidgets have an equal option or is there a simple method to do thi? I haven't found one but i would like to use Bwidgets instead of Iwidgets. Another question which should not be a problem, but at the moment I just
