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, 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

Thanks Peter, I've started a new R session (in Windows) and managed to get both ways working now : ### THIS WORKS !!! ### library(tcltk) tclRequire("IWidgets") tt<-tktoplevel() combo <- tkwidget(tt,"iwidgets::combobox") tkpack(combo) ### AND THIS WORKS TOO !!! ### tt<-tktoplevel() win <- .Tk.subwin(tt)

[Environment: Win XP, R 2.10.1] I'm trying to install the packages JGR and iWidgets required by the extracat package to make the interactive plots in the package work. I've tried various things, but nothing seems to work. Here is my most recent attempt, followed by my sessionInfo(). Does anyone have any suggestions how to make this work? > > library(extracat) Loading

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

Hi, I am trying to create a drop-down combobox in R TclTk. The following works fine for a ListBox but fails for a combobox: ################# THIS WORKS FINE - CREATES AN EMPTY LISTBOX ## tt<-tktoplevel() win <- .Tk.subwin(tt) .Tcl(paste("listbox",.Tk.ID(win),.Tcl.args())) tkpack(win) ################## THIS FAILS - ATTEMPTS TO CREATE A COMBOBOX ## tt<-tktoplevel() win

Hello... Curious to know whether the TK extensions “Tktable” and “Iwidgets” will be included in future versions of R (full installation). These are key components of GUI construction and would be very useful in my current R-tcltk endeavors. I realize that I could just install a version of ActiveTcl, which includes the extensions; however, my goal is to eventually distribute my work keeping

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?

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
