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, 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

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",

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

Why the variable archOp does not take the value that be chosen in the menubutton?, therefore always remains as a white one, I intend to charge the direccion of open files in a vector and then to elect with the menubutton with which to work but not functions thanks.Ruben library(tcltk) arch<-tclVar(init=" ") archOp<-tclVar(init=" ") vectPath<-c()

Dear R-Community, I need the Img tk extension for my R package. It all works on my Ubuntu machine (libtk-img). However I experience a great deal of trouble when I try to install the package on OSX 10.5 or 10.6 (in fact I'm not able to do it). As I understand it, the ActiveTcl with it's teacup package manager do not have an effect on the the x11 tcl installation which R accesses. MacPorts

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? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause.

Hi, I've been trying to install R on Red Hat Linux 9 for some potential users of my R/TclTk application. I tried using the rpm for R 1.7.1 for Red Hat Linux 9. It told me that I needed: libtcl8.3.so so I looked for a binary release of Tcl 8.3.x on http://www.tcl.tk/software/tcltk/8.3.html but found that the link to the Tcl 8.3.x binaries pointed to ActiveTcl 8.4.x . I couldn't see
