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) .Tcl(paste("iwidgets::combobox",.Tk.ID(win),.Tcl.args())) tkpack(win) But they both fail in my old...

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 combobox > combo <- tkwidget(top,"BWidget::combobox") Error in structure(.External("dotTcl...

...tChoice as a variable in R in general. When I run that code, however, and the ask for fruitChoice it says 'error not found'.

...hen 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 still when I try to run any GUI-based program, it gives me the error that TCL/TK were not istalled. In tclRequire(tclPkg) : Tcl package 'BWidget' not found I have a suspicion that I am not setting the TCL_LIBRARY right. When I try to set the TCL_VARIABLE to /usr/bin even then it does not work. What am I doing wrong? Please help. Thanks, Nitin -- ΝI+IИ [[alternative HTML version deleted]]

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

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
