...under R. Now I don't receive the message anymore and it cannot find BWidgets under R. So I'm not even sure that I'm loading the whole tclTk Library anymore(instead of the subset that comes along with R) I've got libtcl8.4.so and libtk8.4.so in /usr/lib My .Renviron file contains: MY_TCLTK=yes TCL_LIBRARY=/usr/lib/tcl8.4 an in my R session: ------------------------------ > Sys.getenv("MY_TCLTK") MY_TCLTK "yes" > Sys.getenv("TCL_LIBRARY") TCL_LIBRARY "/usr/lib/tcl8.4" > tclRequire("BWidgets") [1] FALSE Warning messag...

...ndows currently still ships with Tcl 8.5. Does anyone have experience with linking R under Windows to a Tcl interpreter of version 8.6? When I link R 3.2.2 (installed from the binary on Windows 8) to a custom Tcl installation of version 8.6 (e.g. from ActiveState for both 32bit or 64bit) using the MY_TCLTK environment variable, then loading the tcltk package will result with a tk85.dll not found error. This problem can be ?fixed? by copying and renaming the tk86.dll and the tcl86.dll files in the bin folder of the activetcl installation to tk85.dll and tcl85.dll. However, this setup does not work we...

Hi List, Is it possible to tell R to use tcl/tk 8.5? My R package seems to depend on libtcl8.4.so. However, in Windows it seems to be possible to set TCL_LIBRARY and MY_TCLTK. Is there something similar possible in Linux? I have installed: $ rpm -q R R-2.3.1-1.fc5 $ locate libtcl8 /usr/lib/libtcl8.4.so /usr/local/lib/libtcl8.5.so

...megawidget initialization error: expected integer but got " --1". I have a fresh binary install of 1.7.0 on Win2000 machine. I observed this behavior with the Tcl library included with R and with ActiveTcl 8.4.2 I just installed. I think I have it set-up correctly: my TCL_LIBRARY and MY_TCLTK both point to c:/Tcl where I installed ActiveTcl. I also have c:/Tcl/bin on my path - to avoid possible interference with cygwin Tcl I have the following in my Rprofile: Sys.putenv("Path"="c:/Tcl/bin;c:/cygwin/bin") I can run the other demos successfully. I also just r...

....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 installed ActiveTcl and I have added the Tcl\bin directory containing the DLLs to my PATH environment variable. I can load the tcltk package with library(tcltk) and use all of the standard widgets, but tclRequire("iwidgets") fails : > tclRequire("iwi...

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
